Abstract: The photovoltaic sunshade component has been widely used in BIPV for its artistic and energy conservation, In this paper, a mathematical model of photovoltaic sunshade component was established, the influence of its oblique angle, ratio of stretching out and the install height on shading coefficient was analyzed specifically. Considering the requirement of generating electricity, an engineering project was constructed as the optimum modeling parameter, eventually, a universal design parameter of photovoltaic sunshade component was obtained.

Abstract: In order to illustrate the mechanism of supporting, maintain the safety and keep the stable of underground projects, it is of great significance to study the transverse effect of bolted discontinuous rock mass. With a 3D model and corresponding physical simulation, analyzing the testing results of the bolt stress, rock stress and displacement discovers some new findings. Besides its reinforcing effect to the rock mass, the bolt has a negative effect on the discontinuous rock mass by its so-called ‘railway effect’ under shear loading. The finding of this bolt function will help to further understand of bolting mechanism and it is very important to raise the safety of bolt supporting design. Furthermore the effect grade is a positive correlativity with the bolt diameter, and the shear displacement is one of its necessary conditions.

Abstract: With the development of social economy, the traffic burden is increasing, and many bridges appear damage at different degree because they have been overloaded. There are many special type loads beyond specification range in the overloaded vehicles, however the carrying capacity evaluation of the bridge under the special type load is different from the conventional methods. Take the reinforced concrete bridge built in the 90's of the 20th century for example, this paper analyses and discusses the existing carrying capacity evaluation method of the bridge when the special type load beyond the design standards drives on the bridge, as well as the whole process of analysis, loading, and the results analysis of the loading test in detail. Finally, the results of the study have a high guiding significance to the similar work.

Abstract: The calculation of truss deformation under static loading is studied in this paper. First, an experiment was conducted to get the truss deformation for calibration. Second, the deformation was calculated by the principle of virtual work of structural mechanics and by Ansys. The calculated results agree well with the test result. Finally, some suggestions are presented to the calculation of more complicated truss structures.

Abstract: According to the survey，there are 7.057 billions of residents on this planet , facing a serious situation that land is only 29% of the star area, on which plain takes 1/3 and remains are mountainous region. With such a situation of lower residence and higher population, we must take it into consideration that living states in mountainous region. Due to resent years of high speed financial development among China, residential housing areas increase nearly 2 billions sq per year, among which rural residential building takes half part of the total national area. How to improve living condition and concentrate on low-carbon energy saving would be a required course of every modern architect. Traditional residence in mountainous would offer us modern architects many great ideas. This paper is going to research those out-standing features of Sandu village of Yangquan, Shanxi province.

Abstract: Sustainable building refers to this buildings that can save resources (such as energy, land, water, materials), protect environment and reduce pollution, provide health, application and efficient use of space for the people, and also provide natural harmonious architecture in the whole cycle life. Foreign and domestic development situation of sustainable building design was introduced in this paper. The design strategy of sustainable building is put forward, and the typical case of Sustainable architecture is analyzed. The purpose is to provide a reference for future sustainable building design.

Abstract: Through the northwestern cave homes’ distribution and some research work, the article analyzes its spatial form and existing problems. And combined with the modern building technology, in view of the traditional cave dwelling interior space drab, tightness in the dark wet and poor seismic performance shortcomings,the article, mainly from the perspective of spatial form of traditional cave dwelling potential ecological advantages, puts forward such problems as the innovation and development of cave dwelling space reference.

Abstract: In recent years, continues development of China urbanization gradually increases the energy consumption of buildings. Studies on the life cycle energy distribution of buildings have practical significance to determine energy policy formulation and adjustment. Based on previous studies and the composition of the life cycle energy consumption of buildings, this article constructed a life-cycle energy consumption model, and established the calculation methods of initial embodied energy, operational energy, reset embodied energy ,dismantle embodied energy and recycle embodied energy separately. Based on ICE material energy data and combined rating per machine per team, this article calculated the life cycle energy distribution of a building in Nanjing. We found that the life cycle energy of buildings obeyed normal distribution, the operational energy accounts for a large proportion and it decreases with the decreased life cycle of buildings. The recovery of operational energy can reduce the proportion of the initial embodied energy. Considering the studies, in order to meet the characteristic of the buildings in China which have short life cycle, we should focus on the development of building materials recycling and reusing.

Abstract: The finite element analysis software-ANYSIS is used to calculate and analyze the deformation and mechanical performance of the abnormal joints core zone of variable beam shaped (reinforced concrete beam) under the positive and negative symmetric loads (simulate earthquake loads) . With the method of control variables, multiple finite element analysis models are set up and the focus is to explore the crack development, stress distribution and failure pattern in different stages. The compared conclusion shows that the shear failure of small joint core is the key to the whole joints core area for variable beam shaped.

Abstract: By adopting a hinged form at the bearing joints of the traditional framework anchoring systems, a new overall flexible slope supporting system—hinged framework anchoring system was established. The system can not only keep anchoring force transmission mechanism to ensure the overall slope reinforcing effect, but also allow the slope to have finite deformation to dissipate energy (under dynamic mechanism). A flexible hinged frame anchored theoretical model is established and solved based on finite difference program FLAC3D. Strength reduction technique is used to evaluate the slope stability and obtain the factor of safety. By the comparative analysis of rigid frame connected supporting system, internal force and deformation of each component part of different supporting system are compared. The results showed that: the flexible framework anchoring system can effectively control the slope sliding to ensure the slope stability. At the same time, the flexible supporting system had obvious advantages of improving its stress states compared to the traditional framework anchoring system. With a new framework for anchoring flexible hinge supporting system was proposed and analyzed, a new design idea in slope reinforcement is provided, while a basis for the application of the new supporting system is provided.
