Discussion for Solar Energy Application of Green Buildings Zhang Jian1, He Cuntao2, Liang Chen1, Cailiang1 1College of Civil Engineering, Shenyng Jianzhu University, Shenyang110168, China; 2The Second Company of the Third Bureau of China Construction Group, Shenyang 110013, China Keywords: green building Solar Energy Technology Photoelectric curtain wall Vacuum tube type solar water heating system system of sunshine chasing (reflecting) mirror Working principle Abstract: Green building, a kind of sustainable development and energy-saving buildings, has a very important significance for alleviating strained resources, protecting the environment to reduce pollution; And the solar energy as a kind of important renewable energy, with features of energy saving, environmental protection and natural, is more and more widely using in the green building.
Photoelectric curtain wall is one of important products in the solar energy utilization of photovoltaic power engineering today, it makes full use of solar energy more in green building.
But it was installed and used only by one engineering in the domestic.
And photoelectric curtain wall system and sunshine chases (reflection) lens system are less used, especially the sunshine chases (reflection) lens system which is the first time used in the domestic engineering.

Introduction T-beam bridge is widely applied in bridge engineering, the load transverse distribution factors of T-beam bridge is an important factor to be emphatically considered in the design of this kind of bridge[1-4].The load transverse distribution factors has great influence to T-beam bridge, and the diaphragm beam has grate influence to load transverse distribution factors of T-beam bridge[5-6].So it has great significance both theory and engineering application to study the diaphragm beam's influence to the load transverse distribution factors of T-beam bridge.
Fig. 5 Schematic diagram of experimental loading device/ mm Fig. 6 Physical figure of experimental loading device Comparison on experimental results and theoretical value Get the experimental data of the T-beam bridge at every working conditions, and mechanical analysis of the T-beam steel bridge model is carried out by Midas/civil finite element software, and get the strain and deflection of the model under each loading level.
T-beam bridge with diaphragm beam can bear more than that without diaphragm beam at the strain. 3) The diaphragm beam can reduce the load transverse distribution factors under the concentrate load. 4) In practical engineering, the T-beam bridge should be set diaphragm beam to enhance the overall stiffness of T-beam bridge, and let the bridge more secure.
