| With the growing number of world-building, the building energy consumption beyond the industrial energy consumption and transport energy consumption, became the first social energy consumption. In unrenewable resources decreasing circumstances, solar energy caused everybody attention for its clean and infinity. After continuous development and innovation, bilding integrated solar energy has become the future development direction of the building, especially the photovoltaic technology and building integrated applications on the large span space structure become a major bright spot in the construction industry.Development of human civilization can not prevent the occurrence of natural disasters, earthquake disaster as natural disasters, with an irresistible destructive disaster. People can not afford the serious losses after the earthquake earthquake. We can know from the circumstances after the happend earthquake, in order to make the victims can receive timely treatment then resume normal life as soon as possible, it is necessary to build the large span spatial structure refuge for post-disaster use, which have strong seismic performance and use solar energy to provide energy. Accordingly, this paper designed240m span, cross ratio of0.15in arch truss model, made a preliminary exploration of its solar energy applications, but also study their anti-seismic performance furtherly, the main works are as follows:1. Do an analysis for the principle of solar power generation, solar cell type and its power calculation method, the feasibility of the application of solar energy in building.2. Design240m span steel pipe arch truss equipped with solar power generation equipment. According to the solar power calculation method, calculated and analyzed the entire roof solar power generation.3. In order to meet the requirements of anti-seismic refuge and solar energy application, do elastoplastic dynamic analysis on initial designed structural under the NH wave, do a partial cross-section adjustment on the original design structure through analysis, and compared the results of the two models before and after adjustment.4To further identify the adjust structural whether meet the requirements of anti-seismic shelters and solar energy applications, using NH wave, LOMA wave and RG wave on the adjust structure did seismic response analysis in X, Z, X+0.65Z-bi-directional.This article according to the above two parts content analysis study, draws the following conclusions:1. Compared to other structures, super large span space structure is more suitable for solar applications,through the power calculation of the structure, we can see the solar panels generating capacity is sufficient for the daily life, and as anti-seismic shelters, it can be used as emergency power after disaster2. We can know through comparison, steel amount of adjustment single beam of steel tubular arch truss increased11.2%than the original design structure steel consumption, but the arch truss horizontal anti-seismic capacity increased167%, vertical anti-seismic capacity increased119%, bi-directional anti-seismic capacity increased198%.3. Different seismic waves in the same direction, the maximum displacement value is basically the same when structural damage, and it is less than the allowable deflection value of space frame structure, namely1/250of the structure span.4. The analysis results shows, structural adjustment in the rare earthquake can still be used; Under strong earthquake, the maximum displacement value is less than the maximum allowable deflection of the normal use in the spatial structure, but also this meet the normal conditions of use solar panels. |
