摘要

在近断层地震中

具有速度大脉冲的强震动对建筑物的影响较大。为了描述速度大脉冲

Makris和Roussos提出了由简单连续函数构成的模型

该模型参数较少、形式简单

用来描述实际地震记录中的速度脉冲大多取得较好的效果

但还是有一些记录模拟的结果会出现"丢失"现象

存在一些缺陷。针对此问题

本文提出了2个改进的方法——组合法和镜像法

用来扩展Makris和Roussos模型的适用范围

使其具有更好的适应性。

Abstract

In the near-fault earthquake

strong motion records with a big velocity pulse make a greater impact on the buildings.In order to describe the big velocity pulse

Makris and Roussos made a simple model consisting of a continuous function

with less parameters and simple form.Its results were good.Makris and others used to describe many real seismic records

the simulation results of big velocity pulses are good.But we found that there were some records

in which the "missing" phenomenon occured in the simulation results.The effect was not very satisfactory.For this problem

this paper presents two improved methods

i.e.combination method and mirror image method

to expand the application scope of the Makris and Roussos model

so that it has high adaptability.
