Published: February 2023

Abstract
Generally the concrete consists of fine aggregates, cement, coarse aggregates and water. t had seen that construction cost of materials increases day by day, so we can use an alternative building material that is easily available, economical and improves the strength of concrete. Concrete slabs made of portland cement are used to make rigid pavements, which are placed directly on granular sub grade or on sub base made of granular material. Loads of the slabs are transmitted to the from slabs to the sub grade beneath. So, adequate design and necessarily its life, strength and durability is primary concern now-a–days. The issue focused is the failures of the rigid pavement resulting in deterioration of concrete as joint spalling, shrinkage cracking, corner breaks, durability cracking etc. Many attempts have been seen to maintain and repair the concrete from deterioration. By adding some additives in the concrete the strength, rigidity and ductility of the concrete increases. Cattle bone ash and steel fibers are such additives that are primary focused in this research paper in order to increase the strength of the concrete. CBA has been partially replaced by cement and steel fiber has also been added. The high portion of CaCO2 of CBA in its composition makes it an effective additive to increase the strength in concrete. Similarly, steel fiber can increase the ductility, post cracking, strength resistance to fatigue in the concrete. So, the research paper is focused to have a glimpse over the area of application to increase the strength characteristics of the concrete. This expansion will bring about progress of different properties like tensile strength, compressive strength, and flexural strength of the substantial testing. Thus, the eloquences in engineering potential and quality development of rigid pavement projects.

Authors: Mehta Rahul , Bhandari Mohit 
Published: February 2023

Abstract
This paper represents the effectiveness of the bracing system concerning the seismic performance of steel-concrete composite buildings by comparing 5-storey composite buildings with and without bracings subject to extreme earthquake loads. The nonlinear time history analysis (NTHA) is carried out on the specific building models considered for this study. The seismic response is obtained in terms of different seismic response parameters which are further compared to determine the effect of the bracing system. The results obtained by applying real earthquake records of different near-field & far-field earthquakes were compared for three earthquake response parameters which include base shear, inter-storey drifts, and storey displacements. The bracing system is very effective in resisting the seismic force when subjected to extreme earthquakes as it increases the overall stiffness of the building. The bracing system improves the overall performance of the composite building by reducing the inter-storey drifts and maximum storey displacement under extreme earthquakes.

Abstract
In this exploratory research, PET fibre and silica fume were practised for the intensification of the commonplace concrete. PET fibre was practised at dissimilar proportions of 0%, 0.25%, 0.50%, 0.75%, 1.0%, 1.25% & 1.50%, while the silica fume was practised at 0%, 2.5%, 5.0%, 7.5%, 10.0%, 12.5% & 15.0%. for practising the research work in efficient manner purest form of both kinds of constituents were purchased from India-Mart and the physical and chemical composition details for both the constituents were provided by them. Then several samples were prepared depending upon proportion of PET fibre and proportion of the silica fume. Then all the samplings were examined for resistance against the compressive loads, resistance against the tensile loads, resistance against the flexural loads, quality of the PET fibre-Silica fume based modified concrete and its water absorption. The outcomes of the compressive load application test reveals that with the usage of the silica fume most significant value was attained at 15 % practice of the silica fume. Then this silica fume was utilized in combination with the PET fibre. In this particular case most, significant value was gotten at 15% practice of the silica fume and 1.25% of PET fibre. These kinds of outcomes were mainly attained due to the highly reactive nature of the silica fume and it reacts with the cement in a more reactive manner and leads to improved outcomes. The outcomes of the flexural loads and tensile loads application test were similar to the application of the compressive loads and the maximum value in both the cases were attained at 15% practice of the silica fume and 1.25 % application of the PET fibre. It was mainly due to the high tensile strength of both silica fume and PET fibre. The outcomes of the rebound hammer and UPV examination were similar and the best and optimum results were gotten at 15% practice of the silica fume and 1.25 % application of the PET fibre. These kinds of outcomes were mainly attained due to the highly reactive nature of the silica fume and it reacts with the cement in a more reactive manner and leads to improved outcomes.

Published: February 2023

Abstract
For four sample decades, the study examined the long-term climate trends along with the area and production changes in Chamba district of Himachal Pradesh. A database was collected for maximum temperature (Tmax ), minimum temperature (Tmin), and rainfall, and for the area and production of apple for the four representative decades of Chamba region of Himachal Pradesh. It has been observed that trends indicated that temperature in this district showed an increasing trend and precipitation (rainfall) showed decreasing trend. Temperature, rainfall was the main parameters collected along with other meteorological parameters. The minimum and maximum temperature & rainfall data were collected from the records of government departments for the period of at-least 25-30 years. Long term trends were generated to check the change detection. The minimum temperature in Chamba district has shown an increase of 0.36°C and maximum temperature increase by 0.3°C and annual rainfall decreased by 117.95 mm in 36 years. It has also been observed that many farmers are now opting for industrial crops like mushroom, flowers, off season vegetables because of climate change. Due to an increase in temperature, apple crop is getting less chilling hours, which is somehow affecting the quality of fruit. More long term research efforts are required to be conducted in Free Air Temperature Enrichment (FATE) which can enhance this study. This study also indicates that there is an increase in area and production in Chamba district but fluctuation is seen in productivity. Shifting to higher elevation might be temporary solution to meet the chilling requirement but a proper measures need to be taken. The area under apple cultivation has increased substantially from a mere 400 hectares in 1950s to 11. 4 lakhs hectares in 2020s but fluctuation is observed in the productivity of the crop. Considering the vital role that apple has in the economy of Himachal Pradesh, there is a need to study the production and productivity of the apple crop
Comparative analysis of building with shear wall & diagrid structure
Authors: Jaiswal Rishav , Mahajan Ankit 
Published: February 2023

Abstract
The rapid growth of urban population, the lack of spaces in the cities and the high cost of land have already forced the developers to focus on the high-rise buildings. As the height of the building increases, the lateral load resistant system become more important than gravity load resistant system. That’s why it is important to define lateral load resistant system in high rise buildings. So the lateral load resistant systems such as shear wall and diagrid are introduced since they are better in terms of cost, aesthetic and performance. However, the diagrid structural system has become more popular these days due to its efficiency and aesthetic look provided by the unique geometric configurations of the system.
In this study, a comparative analysis has been done on the buildings with different lateral load resisting systems. Five different building model of G+9 story building has been modeled with shear wall and diagrid structure to compare their performance. The design is analysed for seismic zone V and medium soil condition as per IS 1893:2016 using ETABS software. The building is kept the same except for the lateral load resisting system. From the patterns of the results, it was concluded that building models with the combination of shear wall and diagrid module has better performance in term of the maximum story displacement, story stiffness, story drift, base shear, and time period.

Abstract
The earthquake is the most devastating and unexpected natural phenomenon, causing massive damage to both human lives and infrastructure. In this study, two different irregulars Reinforced Cement Concrete (RCC) building plans of 25th story buildings with the ground floor (G+25) and 9th storey buildings with the ground floor (G+9) were subjected to four different zones making a total of eight model structures to test their ability to withstand gravity and seismic loads. The design was response spectrum method (RSM) then subjected to an earthquake load in accordance with Indian Standard (IS) 1893. The earthquake performance is evaluated on the basis of the structure’s design, serviceability, and earthquake power using an extended three-dimensional analysis of building systems (ETABS). The behaviour of building irregularities under seismic loading is investigated in this work. In this study, it has been compared the results in terms of max story displacement, max story drifts, and base shear. It was found that the model in zone 5 has maximum story displacements among all other models as well as higher max story drifts and base shears for both plans of G+9 and G+25. From the result, it was concluded that both the building models in the lower zone showed better performance in terms of max story displacement, max story drift, and base shear.

Abstract
The topic “Dynamic analysis of multistoried irregular building using Staad pro”is a topic of major concern as with industrialization and development most of the population opt for urban areas. The structural stability of a building has to be compromised in order to attain lateral loads due to earthquake and wind in concurrence to gravity loads. Hence, it is quite evident for a structure to have sufficient strength and enough stiffness to resist loads. Design and analysis nowadays are convenient as well as affordable just because of the availability of computers and specialized programs. The multistoried building is designed using software Staad pro v8i. The paper deals with analysing three different models of irregular multi story building (G+10) with a height of each floor as 3m having response factor as 5, importance factor as 1.2, soil type as medium soil, structure type 1 with a damping ration of 5% is taken into consideration. The loads being used in the analysis are Dead load which is considered as per IS 875 part 1, live load as per IS 875 part 2 and seismic load as per IS 1893 part 1. The beams, columns and slabs are celibately designed in software. Results of three models are then compared as per storey drift, displacement and base shear.

Published: February 2023

Abstract
Urbanization is taking place at a very fast pace in India. The migration of people from villages to cities is putting a tremendous pressure on the infrastructure in all the major cities. Due to the lack of expertise, the Municipal Authorities continued to dispose of the MSW by dumping it in open areas. The fires and other constant problems at dumping ground along with ground water contamination due to leachate causes a lot of opposition from Nongovernment Organizations (NGOs). Municipal solid waste (MSW) is diverse in nature and includes biodegradable materials as well as paper, plastic, rags, metal, glass, and pieces of metal. Aside from these additional components, MSW also includes scrap materials, waste papers, dead animals, abandoned chemicals, paints, toxic hospital waste, and agricultural leftovers. The biological waste produced by clinics, hospitals, nursing homes, pathological laboratories, blood banks, and veterinary centres has until to this point also been dumped at the dumpsite with MSW. Solid waste is a waste type that includes predominantly household waste which sometimes includes the addition of commercial waste collected in a given area. Pune Municipal Corporation (PMC) is responsible for collection, storage, segregation, transportation and disposal of all solid waste generated in the city. In the present research work describes an attempt to assess the different parameters on the leachate collected from the Mantarwadi dumping site, Pune. Leachate from landfills has the potential to contaminate both surface and ground water if left unchecked. Within a single location, the leachate’s composition varies substantially. The age of the landfill, the types of trash, the degree of decomposition that has occurred, and the physical alteration of the garbage are some of the variables that determine composition. Once groundwater is contaminated, it is uneconomical to retrieve the same. The waste from Pune City is disposed of by the Pune Municipal Corporation at Mantarwadi (Urali devachi depot), which is located 20 km away from Pune City. At Mantarwadi, over 1200–1300 metric tonnes of solid trash from the Pune municipal area are disposed off each day.

Published: February 2023

Abstract
Plants have majorly been used for medicinal purposes since the Vedic era. Since the dawn of time, flowering or aromatic plants have been playing an important part in humanity. Medicinal Plant-based treatments are currently used by approximately 80% of the world’s population due to their low cost, high availability, fewer side effects, and other factors. One of these plants is Rosa sericea, sometimes called the silky rose. Rosa species is a Rosaceae genus that generates medicinal natural products like polyphenolic and terpenoid compounds, which are utilized in a range of traditional medicines. It is indigenous to some parts of northern India and in some parts of southwest China. Medicinal effects can be found in almost every part of the plant. Fruits and seeds are the parts of plants that are utilized as remedies. Rosa plants are used to cure many diseases like headaches, cancer, liver complications, etc. Many fruits of this genus are highly rich in minerals and vitamins, particularly rich in vitamins A, C, and E, and flavonoids and other bioactive substances are also present. Rosa sericea has been used in various research for its pharmacological properties, there is a gap or lack of knowledge on production methods. The review’s goal is to provide academics, healthcare practitioners, and politicians with a systematic way to organize massive amounts of incomprehensible data so that they may quickly incorporate existing data and make balanced decisions. The findings of this study suggest the extension of traditional medicinal usage of the examined plants for the treatment of all of the diseases indicated above. The current review seeks to incorporate some available information on the ethnobotany, phytological, and ecology of this genus as well as its therapeutic features.
