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

本研究主要围绕“分布式加载系统在线地震反应模拟器”和“基于Internet的分布式地震反应分析”两个课题展开，与远在他乡的国内外研究人员进行合作。我们考虑建筑物的部分结构的分析和实验之间的相互作用。从个别局部结构的表现出发，自由运用各研究者的技术知识，阐明整体建筑的抗震性能。本文将这种评价方法称为“协同抗震性能评价方法”，通过对“无压支撑”和具有新功能的振动控制结构单元--“无滑移型外露柱脚”的研究，阐明了”协同抗震性能评价方法“通过增加振动控制结构单元来提高抗震性能的作用，并对“协同抗震性能评价方法”的抗震性能进行了评价。我在一个分布式装载系统中做了八个如下的功能添加来实现这些评估。首先，我在分布式装载系统中处理了三个关于装载方法的研究问题。(1)夸大了超调量。(2)多轴加载方法。(3)塑性加载条件的保持。然后，我们致力于以下三个研究问题，涉及到一个控制程序，以集成一个分布式加载系统。(1)实现了数字信息的通信功能. (2)任意设置边界自由度。(3)具有位移/载荷复合控制功能的设备。在将OS方法应用于主机程序时，我们遇到了以下两个研究问题。(1)OS方法的实现。(2)加载系统摩擦力引起的一个问题的求解。

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.
