The purpose of this project is to construct a more rational earthquake-resistant design method, referred to as "earthquake-response constrained design method." The proposed method enables one to find the set of member stiffnesses of the building frame which exhibits local responses of a prescribed distribution to design earthquakes. The following results have been obtained.(1)Earthquake-response constrained design methods have been developed for plane shear buildings, for elastically supported plane shear buildings, for three-dimensional shear buildings and for plane braced frames.(2)A series of time history analyses have been conducted on frames designed by means of the proposed method subjected to ten artificial earthquakes and the validity of the proposed method has been verified.(3)The earthquake-response constrained design method has been extended to one-dimensional distributed-mass structures. A procedure for finding the mass distribution of the structure which exhibits a specified response curvature distribution has been presented.(4)A new concept called an ordered set of optimal solutions of similar regular trusses has been introduced. A practically powerful method has been presented of approximate optimum plastic design of large regular trusses on the basis of this concept. A sequential optimal truss generator has also been devised for regular trusses on the basis of an ordered set of optimal solutions with respect to the fundamental natural frequency.(5)A problem of designing a multi-story multi-span plane frame for a specified set of member-end fiber strains under a set of static design loads has been formulated. Several classes of closed-form solutions of practical significance have been derived to the problem.

本项目的目的是构建一种更加合理的抗震设计方法，简称“地震响应约束设计方法”。所提出的方法使人们能够找到建筑框架的一组构件刚度，该组构件表现出对设计地震的规定分布的局部响应。取得了以下成果：(1)建立了平面剪力建筑、弹性支撑平面剪力建筑、三维剪力建筑和平面支撑框架的地震响应约束设计方法。(2)对采用该方法设计的框架进行了10次人工地震的一系列时程分析，验证了该方法的有效性。(3) 地震响应约束设计方法已扩展到一维分布质量结构。提出了一种求具有特定响应曲率分布的结构质量分布的方法。(4)引入了相似规则桁架最优解有序集的新概念。在此概念的基础上，提出了一种实用有效的大型规则桁架近似优化塑性设计方法。基于基本固有频率的一组有序最优解，还为规则桁架设计了顺序最优桁架生成器。(5)提出了在一组静态设计载荷下针对一组指定的杆端纤维应变设计多层多跨平面框架的问题。该问题已经导出了几类具有实际意义的封闭式解。
