项目摘要

The purpose of this research is to develop a rational and practical computer aided structural design system, which is intended to maximize the efficiency of structural engineers, for high-rise buildings (including those with passive dampers). The main results of our research include:(1) We have proposed an optimum design method for a 3D building frame having lubber isolators and viscous dampers at a mid story. The basic idea behind the proposed optimum design method is to expand a shear frame model to a full frame model composed of beam elements. This is an inverse approach to the reduction of the full frame model to the share frame model, which is often used in ordinary structural design.(2) We have extended the optimum design method developed last year for building structures based on "the calculation of response and limit strength," which was introduced in the Japanese building code-revised in 2000, by taking into account the effect of response amplification in the ground surface.(3) A new stiffness design method has been developed for shear buildings subject to a design earthquake with non-monotonic displacement spectrum. The objective function that is a combination of the fundamental natural period which represents 'cost' and the level of the maximum displacements which represents 'performance' is introduced into the design method to find a set of story stiffness under response constraints. We have further extended this method so that it can deal with multiple design earthquakes.

本研究的目的是开发一个合理、实用的高层建筑（包括设置被动阻尼器的高层建筑）计算机辅助结构设计系统，以最大限度地提高结构工程师的工作效率。本文的主要研究成果包括：（1）提出了一种中间层设置阻尼器和减隔震器的三维框架结构的优化设计方法。提出的优化设计方法的基本思想是将剪力框架模型扩展为由梁单元组成的全框架模型。这是一个逆的方法来减少全框架模型的共享框架模型，这是经常使用的普通结构设计。(2)在2000年修订的日本建筑规范中引入了“反应和极限强度的计算”，并在去年开发的建筑结构优化设计方法的基础上，考虑了地面的反应放大效应。(3)本文提出了一种新的剪切型结构在非单调位移谱设计地震作用下的刚度设计方法。该设计方法将基本自振周期和最大位移水平作为目标函数，以结构的基本自振周期和最大位移水平作为目标函数，得到了一组反应约束下的层间刚度。我们进一步扩展了该方法，使其能够处理多个设计地震。
