Seismic Response Analysis of Buckling Restrained Frames
Authors: Zhang Xuyang 
Published: July 2020

Abstract
The frame structure system uses additional buckling restraint support, which greatly improves the shear strength and lateral stiffness of the entire structure, and plays a positive role in reducing the displacement between layers and the overall displacement of the structure. When the additional buckling restraint support is used in the frame, the hysteresis curve of the system is fuller, which greatly improves the energy consumption capacity of the structure. The descending section of the stent skeleton line breaks through the traditional limitations, and its descending degree slows down as the displacement increases. The lateral stiffness of a buckling restrained frame is poor, and usually requires large beam and column sections to meet the requirements. Under the action of earthquakes, the support of buckling restrained frames is prone to buckling and instability, resulting in a sharp decline in its seismic resistance. The purpose of this paper is to analyze the seismic response of buckling-restrained frames. In terms of methods, this article mainly starts from the design method and principles of buckling restrained braced steel frame, and then designs and discusses the buckled restrained braced steel frame. Then it designs the BRB size and uses the Perform-3d software to build a nonlinear structural model. Use time history analysis to analyze some possible problems in the building. In terms of experiments, this paper mainly analyzes the seismic response of a building, and introduces the situation of the building and its analysis in terms of earthquake prevention. From the four strong earthquake records recorded in this paper, it can be seen that the maximum value of the seismic acceleration time history increases with the increase of the earthquake intensity. And the earthquake impact of rare earthquakes will be greater than that of more frequent earthquakes under the same intensity. From the data of structural analysis, the period of the original structure is greater than the period of the BRB structure under the same mode shape. As the mode shape increases, the period difference decreases and converges.

Authors: Jiang Hao 
Published: July 2020

Abstract
In the process of economic construction, the development of the economy will have an impact on the environment, whether it is good or bad. This paper selects carbon dioxide emissions as an indicator of environmental quality. And the population in each period of each country, the per capita electricity consumption of each country, the proportion of coal, oil and natural gas power generation in each period of each country, the ratio of education expenditure to GDP in each country, the ratio of forest area in each country to the national area, and the price of gasoline in each period of country as six explanatory variables. The empirical analysis of the above variables yields conclusions that the economic development will have a negative impact on the environment and give relevant recommendations.

Authors: Zhang Yishan , Ning Zhi , Lv Ming 
Published: July 2020

Abstract
In this paper, the biodiesel/ethanol gas-containing fuel droplet was numerically simulated at room temperature. The growth characteristics of the bubble growth process were obtained, and the influencing factors affecting the bubble growth and micro-explosion process were explored. Studies have shown that bubble growth and droplet micro-explosion at room temperature are dominated by the pressure difference between the inside and outside of the bubble. Within a certain range, reducing the initial radius ratio of droplets as much as possible can also promote the bubble growth and micro-explosion of droplets. The proportion of fuel in the droplet will also affect the bubble growth and micro-explosion characteristics.

Published: July 2020

Abstract
Cement Asphalt Concrete (CAC) is a newly developed cold-mixed pavement material at room temperature. In this paper, a kind of cement fast-cracked emulsified asphalt mastic and a gradation of stone mastic asphalt was used to obtain a high-performance pavement material. This material improves the gradation by calculating volume parameters and observing the state of the concrete, and then we determine the optimal cement asphalt mastic content through specific gravity, Marshall stability value and aggregate wrapping state. Finally, the Marshall stability value, flow value, indirect tensile strength and Cantabro loss were used to evaluate the performance of Stone Mastic Cement Asphalt (SMCA), Continuous-graded Cement Asphalt (CCA) and SMA. This paper shows that SMCA’s technical performance is relatively similar to CCA, and the Cantabro loss is much lower than CCA. In comparison with SMA, except for flow value, other performances are higher than SMA.

Abstract
Philippine is one of the countries near in the Pacific Ring of Fire. In recent years, several moderate to high seismic activities happened that leads to casualties, deaths and damages in different structures. Manila is the capital of the Philippines with a population of almost 1.8 million. Many structures have been considered as old and unsafe and with an impending earthquake, it is essential to rehabilitate these structures. The imminent danger of the West Valley Fault when it moves is known throughout the metro manila and other neighbouring regions. The damage and casualties that will sustain from the possible 7.2 magnitude earthquake is fatal. Conducting mitigation programs is critical for it will greatly benefit the government and the people. Rapid Visual Screening (RVS) is an effective and efficient way of assessing the building’s structural integrity. This methodology is used to assess the structure’s seismic risk by visual observation of the exterior and interior of the buildings and a data collection form. RVS was applied in 26 hospital building’s located in Manila and the outcome of the assessment has shown that only 6 hospital buildings proved to be seismically adequate when using the level 1 data collection form. RVS is an effective tool in providing initial insight in the building’s vulnerability to seismic event.

The resiliency of transportation infrastructures has been a major concern for the continuity of road services. In order to assess these issues, road network analysis is crucial to investigate the functioning of the existing road network and pinpoint each critical road segment. This enables early preparation for road operators and planners to focus on the road segment user most dependent on of which will be impacted most in case of disruption. This paper aims to introduce a method integrating different network analyses using a combination of three measures namely road segment length, betweenness centrality, and road density to identify critical road segments. The result shows the relationship between the different modes proposed with respect to the topological data implemented and concluded as the critical value of each road segment. This paper also includes the application of the methodology in a national scale region of Peninsular Malaysia road network.

Published: July 2020

Abstract
Within the southern region of Peninsular Malaysia, Johor has experienced the most severe flood disasters with almost 9,000 evacuees between the year 2012 to 2017, which the locals attributed to poor flood management and administration. Eight main responding agencies identified based on NSC Directive No. 20 were surveyed in Segamat, Johor, in order to assess current perception and practices, as well as ascertain aspects of flood management that need improvement. A self-administered questionnaire was used which focused on the agencies’ flood response capabilities, and five key determinants towards effective disaster response namely collaboration, predisposition, information sharing, coordination among agencies, and preparedness. Results from the survey among 80 respondents found that responding agencies in Segamat have a positive perception of their planning and responding capabilities. Based on a checklist of preparedness measures, the majority of respondents were found to have a high level of flood preparedness, particularly for emergency coping and restoration works. However, while the findings showed that the agencies have high confidence in responding to flood individually, there are opportunities for improvements in their capabilities to work and respond cohesively with each other and with the local communities.

Abstract
Climate change is considered as a major driving factor to intensify the challenges to the ecosystem. Critical flow condition which is occurred under climate change could lead issues to ecosystem and biodiversity. In contributing to this concern, Soil and Water Assessment Tool (SWAT) and Indicators of Hydrologic Alteration (IHA) were integrated to define the impact of climate change relevant to ecosystem. SWAT model presented a good performance on simulating daily streamflow in this research. As the result, model calibration was evaluated with statistical indicators of NSE=0.63, RSR=0.61, and PBIAS=-5.42%, while model validation obtained better performance of NSE=0.71, RSR=0.54, and PBIAS=-5.04%. The developed model was used to simulation streamflow under climate change scenarios. Three projected climate change models (GFDL-CM3, GISS-E2-R-CC, IPSL-CM5A-MR) with different two Representative Concentration Pathways (RCP2.6 and RCP8.5) in the 2030s, 2060s, and 2090s were selected. Results indicate that timing, frequency, magnitude, and variability are more likely to have great changes for GISS-E2-R-CC with both emissions, while result indicates small changes with GFDL-CM3 and IPSL-CM5A-MR models.

Abstract
Recently in the field of disaster risk management, the applications of rainfall data from X-band Polarimetric radar are rapidly increasing due to the advancement of radar technology and analytical tools. In most cases, these rainfall data are used in the development and application of the meteorological and hydrological models. One of the typical purposes of such models is to report and disseminate disaster information such as rainfall to the government, related agencies, and the public for disaster prevention or mitigation. To accomplish this, the reliability of rainfall data from X-band Polarimetric radar is one of the most important factors as the data are the fundamental input. Equally important is the appropriate analytical method of the data to ensure the predicted rainfall information based on the collected data is reliable and safe to be used for further development and applications. Under such circumstances, this paper aim to investigate and evaluate the types of analytical methods for rainfall estimation by using X-band Polarimetric radar data. Content analysis was carried out and as a result, the statistical analyses were found as an appropriate analytical method to determine the reliability of rainfall data from the X-band Polarimetric radar. Further, the result from this study will be used to apply to a set of actual rainfall data from X-band Polarimetric radar and Automated Meteorological Data Acquisition System implemented in a region in Japan.

Abstract
Recent natural disaster events have caused damage to structures and led to loss of lives. Steel structure industrial building is one of the important structures that needs to be examined as these structures can have huge impact on the surrounding areas. Therefore, this study presents the fragility curves and performance curves of steel structure industrial building under earthquake loading. The structure consisted of beam, column, and bracing were modelled using three dimensional finite element modelling. The fragility curves were obtained for the structure, and the performance curves were developed based on lateral load, which was affected by the geometry of the building. Three records of far-field ground motion and three records of local ground motion were used for incremental dynamic analysis (IDA). The five levels of performance stated by FEMA-273, namely, operational phase (OP), immediate occupancy (IO), damage control (DC), life safety (LS), and collapse prevention (CP) were used as main guidelines to evaluate the structural performance. Results showed that, probability damage for operational phase, OP started at 0.19g and 5% of the structure analysed are expected to have immediate occupancy IO, indicating minor cracks to the structure at 0.4g PGA. Moreover, the performance response of the structure to the earthquake was obtained from the study.

Published: July 2020

Abstract
The Sentinel-1 SAR image by the Europe Space Agency (ESA) in the Copernicus Programme is an open source data which offers good data to develop flood inundation mapping. The flood inundation mapping is essential information for local authority personals or researchers to develop flood inventory map. The objective of this study is to develop a flood inundation mapping on November 2017 event to assess its use as potential flood inventory mapping data in Penang. The threshold method was carried out using Sentinel-1 image to extract the flood map. This method is pixel value used to separate the grey image into two parts. The flooded and non-flooded areas can be identified by separating the backscatter lower than the threshold value. The results revealed that the flood inundation maps are able to be extracted out from Sentinel-1 images.

AbstractHeavy rainfall and the associated floods occur frequently in the Malaysia and have caused huge economic losses as well as massive impact on agriculture and people. As a consequence, it is necessary to understand the distribution of extreme rainfall in order to improve the managements in a country. Thus, the aim of this paper is to determine the best method to estimate parameters of Generalized Extreme Value (GEV) distribution that represent the annual maximum series (AMS) data of daily rainfall by using method of moments (MOM), maximum likelihood estimators (MLE) and Bayesian Markov Chain Monte Carlo (MCMC). The daily precipitation rainfall amount of 12 rain gauge stations in Johor from year 1975 to 2008 were used and the AMS data of each year were fitted with GEV distribution. Based on goodness-of-fit tests, namely Relative Root Mean Square Error (RRMSE) and Relative Absolute Square Error (RASE), the performances of three parameters of GEV distribution estimated by MOM, MLE and Bayesian MCMC were compared for each station. The results indicated that Bayesian MCMC method was performed better than MOM and MLE method in estimating the parameters of GEV distribution.

Published: July 2020

Abstract
Anaerobic ammonia oxidation (anammox) is a promising biological wastewater treatment process. It has been widely implemented in many industries due to lower oxygen consumptions besides being an environmental friendly method for wastewater treatment. However, there are several challenges in the process for potential application such as low anammox bacterial abundance and slow growth rate that lower the efficiency of the reaction. Therefore, several factors are being considered during operation of the anammox process. There are various anammox bacteria, which may be enriched using special techniques. Lower nitrogen content of influent brings great challenges for anammox performance due to inhibition caused by ammonium-oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) in nitrification process. This review highlighted the anammox process in various industry as well their anammox bacteria morphology, mechanism and strategies to enrich the bacteria. Coupled anammox process with low strength domestic wastewater requires more research to enable potential application in wastewater treatment.

Published: July 2020

Abstract
Biochar also known as ‘biocarbon’ or ‘biocoal’ is a material that has a charcoal similar property. It is obtained from thermolysis (pyrolysis) of biomass feedstocks and plant matters. It can help the process of eliminating carbon dioxide from the atmosphere. The biochar was considered as waste by industrial plants and considered no additional cost except for the transportation. Biochar was tested for its chemical properties in Department of Science and Technology as a parameter for Simapro. Environmental and health impact were analyzed in this study for concrete with biochar as partial replacement for cement. Different mixtures with zero percent to twenty percent biochar replacement was simulated using life cycle assessment with the help of Simapro. Different sources in Luzon island, Philippines were gathered and found out that sources in southern part of Luzon is the best sources for biochar because of its near location that decreases the effect of transportation. Also, concrete with biochar replacement with or without considereing the effect of transportation yields greater health and environmental impact compared to mixture without biochar replacement.
