shell wall meaning in Chinese

外壳壁

The mechanic character , destroying pattern , the ductile and dissipation energy capacity of this composite structure under the earthquake have been clarified . the stiffness degradation , natural frequency , damping ratio of this structural system with the development of intensity of earthquake have also been investigated . with consideration of the top displacement , drift of story and micro - strain of longitude steel bars , the equivalent shell wall method has been presented in order to simplify the design of such type structure
通过试验，掌握了该结构体系在水平地震荷载作用下的受力特点、变形与耗能性能、结构的破坏形态等力学指标：得到了结构在不同地震烈度条件下的刚度变化、自振频率、阻尼比等动力特性；综合结构的顶点位移、层间转角以及钢筋的微应变，提出了适合于该结构体系简化设计的“等效剪力墙法” 。
