摘要
结合汶川地震实例,从力学的角度出发,阐述了对建筑物进行变形控制的目的,同时介绍了构件抗弯刚度的特点,基于上述原因,探讨了在地震作用下刚度对结构的影响,从而确保结构设计受力合理并获得最佳的经济效益。
Combining with the practical example of Wenchuan earthquake, based on mechanics angle,it expatiates the purpose of distortion control to buildings,meanwhile it introduces characteristic of component anti-bend rigidity,based on above reason,it discusses influence of rigidity to structure in earthquake action,in order to ensure rational stress of structure design and acquire the best ecological benefit.
