摘要:框架结构虽具有良好的抗震性能,但在512特大地震中,被破坏的框架结构房屋所占的比重和由此造成的损失仍相当大。为此,我们现应对框架结构的抗震设计作重新思考,保证框架结构在破坏前具有良好的延性,而结构抗震的本质就是延性,提高延性可以增加结构抗震潜力,增强结构抗倒塌能力。对于有较高延性要求的框架结构,必须使用能力设计法进行有关设计,保证结构的延性,以提高框架结构的抗震性能。

Abstract: Although the frame structure has a good seismic performance, in the May 12 earthquake in the large, the destruction of the framework is still a considerable number of housing, and the enormous loss. To this end, we are now frame structure deal with the seismic design for re-thinking to ensure that the destruction of pre-frame structure has a good ductility, However, the structure earthquake resistance's essence is a ductility, improve the ductility can increase the potential for seismic structure, and enhance the ability of the collapse of the structure. For a higher ductility requirements of the structural framework must be used to
ability design law to carry on the related design to ensure that the structure of ductility, to enhance the structural framework of the seismic performance.
