Collaborative Seismic Performance Evaluation of Vibration Controlled Buildings using Distributed Loading Systems

本研究以“分布式加载地震反应在线模拟器”和“基于Internet的分布式地震反应分析”为研究对象，与远在异地的国内外研究人员合作。我们考虑了建筑物局部结构的分析和试验之间的相互作用。从个别局部结构的行为出发，自由运用各研究人员的技术知识，明确了整体建筑的抗震性能。我们把这种评估方法称为“协同抗震性能评估方法”。我们研究了“非压缩支撑”和一种具有新功能的减震结构单元--“无滑移式外露柱脚”。我们通过“协同抗震性能评估方法”阐明了通过增加减震结构元件来提高抗震性能。此外，为了实现这些评估，我在一个分布式加载系统中做了八个以下的功能添加。首先，我对分布式加载系统中的加载方法进行了三个方面的研究。(1)超调量的夸大。(2)多轴加载方法。(3)塑性加载条件的维护。然后，我对分布式加载系统中的加载方法进行了如下研究(1)数字信息通信功能的实现。(2)边界自由度的任意设置。(3)位移/载荷组合控制功能的设备。当我将OS方法应用于主机程序时，我们努力解决了以下两个研究问题：(1)OS方法的实现。(2)加载系统摩擦力问题的解决。

In this study, we focused in “An Online Earthquake Response Simulator by Distributed Loading System" and "A Distributed Analysis with Internet".We cooperate the domestic and foreign researchers who are in a distant place. We consider interaction between an analysis and an experiment of partial structure of a building. From behavior of individual partial structure, I use technical knowledge of each researcher freely and clarify aseismic performance of the overall building. We call this evaluation method as "Collaborative Seismic Performance Evaluation Method".We studied “Non-Compression Brace" and a “Non-Slip-Type Exposed Column-Base" which is a vibration control structural element having the new function.We clarified improvement of aseismic performance by adding vibration control structural elements by "Collaborative Seismic Performance Evaluation Method".In addition, I did eight following function addition in a distributed loading system to enable these evaluation.At first I wrestled with three following study problems about loading method in a distributed loading system.(1) Exaggerated the overshoot.(2) Multi-axial loading method.(3) Maintenance of plastic loading condition.Then, we wrestled with three following study problems to relate to a control program to integrate a distributed loading system.(1) Implementation of a communication function of digital information.(2) Arbitrary setting of the border degree of freedom.(3) The equipment of a combination control function of displacement/load.We wrestled with two following study problems when I applied the OS method to a host program.(1) Implementation of the OS method.(2) Solution of a problem to be caused by frictional force of loading system.
