所谓刚度就是指单位变形(包括位移、转角等)所需的力,就是能限制作用力产生变形的性质,是工程结构的内在本质。在工程结构设计中应用刚度理论可对结构进行宏观控制,定性定量地进行结构分析,避免结构产生不安全因素,使受力合理并获得最佳经济效益。现在刚度理论研究的基础上,对结构刚度在框架剪力墙结构设计中的应用展开研究与讨论,从而总结归纳出设计中应该注意的问题。
The so-called stiffness refers to the unit deformation (including displacement, corner, etc.) required force, that is, to limit the force generated by the nature of the deformation, is the inherent nature of the engineering structure. Applying the stiffness theory to engineering structure design, we can control the structure macroscopically, analyze the structure qualitatively and quantitatively, avoid the unsafe factors in the structure, and make the stress reasonable and obtain the best economic benefit. Based on the present stiffness theory, the application of structural stiffness in the design of frame shear wall structure is discussed and discussed, and the problems that should be noticed in the design are concluded.
