Authors: Teng Tie Lan , Yuan Jing Feng , Li Qi Ming
Published: December 2014

Over the last 15 years, public-private partnership (PPP) has been acknowledged by many countries as an innovative approach to the procurement of public projects. In the long term of concession periods, Residual Value Risk (RVR) is a structured risk system which would happen at any time in the whole life before transfer of PPP/PFI projects, but consequently causes the Residual Value (RV) that the Government takes over cannot fulfill the specifications. So the RVR factor system was identified through the literature review and a worldwide structured questionnaire survey was conducted to analyze the significance of the identified risk factors of RVR. Furthermore, the formation path of RVR was verified based on Structural Equation Modeling (SEM). Through the proposed formation path of RVR, both the public sector and private sector can monitor the risks to help improve the implementation of PPP projects and achieve PPP project success.

Authors: Wang Yuan Yuan , Sun Lu
Published: December 2014

Using the waste pavement materials can not only save resources such as bitumen and aggregate, but also reduce the pollution of environment. In this study, the high temperature performance and the moisture stability of recycled SBS modified asphalt mixture were evaluated by rutting test, immersion Marshall Test and freeze-thaw splitting routine test. In addition, the low temperature performance of recycled modified mixture was also analyzed by Fénix test whose operation was simple. The tests results illustrated that it was advantageous to improve the high temperature performance of recycled mixture and it has less influence on moisture stability with the addition of RAP. However, it had a significant adverse effect on the low temperature performance for recycled SBS modified asphalt mixture with a large quantity of RAP content. Therefore, it suggests that the RAP content for recycled SBS modified mixture is not too high.

Authors: Li Xue Feng , Fu Zhi , Hui Ying Xin
Published: December 2014

The effects of atmospheric pressure changes on the air entraining capability of air-entraining admixtures was studied using a low-pressure test chamber to simulate plateau environments with thin air and low atmospheric pressure. Results indicate that the atmospheric pressure of the environment significantly affects the performance of air-entraining admixtures. The air content of fresh concrete decreases by approximately 20%–49% when the atmospheric pressure is 50 KPa with respect to the normal atmospheric pressure (101 KPa). The air content of fresh concrete decrease linearly as atmospheric pressure dropped. The higher the air content of fresh concrete mixed in ordinary pressure, the faster the air content of fresh concrete decreases with the drop of air pressure. The concrete with high slump shows more resistance to drop of air-content due to low air pressure than the concrete with low slump. Therefore, in order to meet the design requirements of air content of air-entrained concrete for different constructions in the plateau regions, it is necessary to increase the dosages of air entraining agents to according to different pressure conditions and types of air-entraining agent.

Authors: Zheng Yong Feng , Guo Zheng Xing , Xie Ming
Published: December 2014

Grout-filled mechanical splice system is one of the most important technologies for precast construction. However, due to the high cost of grouted sleeve in Chinese construction market, the implementation of this technology is hindered. In this study, a new type of grouted sleeve was developed with standard seamless steel pipe by cold rolling depression. Utilizing this sleeve, eight coupler specimens were prepared and tested under incremental tensile load and cyclic load. The results indicate that all the specimens provided satisfactory behaviour of which the ultimate tensile strength exceeded the required loading capacity specified in ACI318 and JGJ107. The inner cavity configuration of the grouted sleeve has great influence on the confining mechanism of the splice and on the strain distribution in the sleeve. Because the compressive strength of grout is greatly higher than its tensile strength, the slope of the load-strain response curve of the sleeve under tensile load is lower than it under compressive load.

The cost and benefits have been analyzed of applying SM570 steel to tall buildings in Taiwan. In detail, two 40-story steel buildings are designed for the Taipei Microzonation II. One building has SN490B steel columns. The other also uses SM570 steel for the 1st -to- 14th -story columns. The stress ratios and story drift ratios are limited to 0.9 and 0.005, respectively. The drift demands are then evaluated by using nonlinear time history analyses with 14 sets of ground motions scaled to the intensity for the return periods of 475 and 2500 years. By FEMA 356, the building fragility is further assessed using the drift ratios of 2.5% and 5% for life safety and collapse prevention. It is concluded that the use of SM570 steel saves 140 tons steel in total, approximately 3%. That also reduces the seismic drift demands of the building, greatly decreasing the failure probability against earthquake collapse.

Published: December 2014

In order to extract information of the Mathematical simulation model for the references of land useplanning decision, it analyzed the land use characteristics in shaoyang district of hunan province, then extracted cultivated land, construction land and rural residential land. Typical relation analysis method and spatial gridding Logistic regression analysis method were used to made quantitative analysis of these three types of driving forces and obtain the main influential driving forces for each land use.The results showed that it can provide scientific support for the formulation of the relevant policies ,the fitting degree of the spatial simulation was rather high(f construction land, rural residential land and cultivated land was 79.45%, 89.35%, 95.35% ), it showed that the model can provide theoretical foundation for the regulation of land-use behavior,also help promote efficient for land use fundamentally.

Published: December 2014

CIn order to build gray level co-occurrence matrix suitable to natural texture, a method based on separable criterion was proposed. Combined correlation matrix of feature parameters with character of natural texture, 5 independent feature parameters are extracted from 11 feature parameters of gray level co-occurrence matrix (GLCM). Building factors of GLCM, which is appropriate to describe wood texture, are confirmed by using the separable criterion, when d equals to 2 and g equals to 16.

Authors: Wang Chang , Cao Peng Fei , Zhang Xiang Long
Published: December 2014

The adsorbent of H8Nb22O59·8H2O and the precursor of Rb8Nb22O59 were characterized by X-ray diffraction (XRD), Thermogravimetric and differential scanning calorimetry (TG-DSC), and scanning electron microscope (SEM). The ion-exchange properties of H8Nb22O59·8H2O for Na+ and K+ were also investigated, including the saturation adsorptive capacity, distribution coefficients and separation factor. The results show that the crystallinity of Rb8Nb22O59 was affected by the calcination temperature. The structure of Rb8Nb22O59 was not changed when Rb+ was extracted from Rb8Nb22O59, indicating that this process was topotactical. The calcination temperature and pH value had a significant influence on the ion-exchange capacities of H8Nb22O59·8H2O for Na+ and K+. Specifically, the uptake amouts of Na+ and K+ by H8Nb22O59·8H2O increased with the calcination temperature, while the distribution coefficients of Na+ and K+ for H8Nb22O59·8H2O increased with the pH value. Moreover, the separation factors for K+ was larger than that for Na+ and it increased with the increase of calcination temperature. Overall, the improvement of the crystallinity of H8Nb22O59·8H2O was beneficial to its selectivity for K+.
