摘要

在目前古建筑研究领域中，对木构架的抗震分析绝大多数都是在普通地震动作用下，而对长周期地震动作用下的木构架动力研究相对较少。因此，本文主要选择了两条典型的长周期地震波和两条普通的地震波，对古建筑木构架整体结构在两类地震波作用下的动力响应进行比较研究。研究表明，台湾集集地震波和Loma-Prieta 地震波的长周期成分要比El-Centro地震波和兰州波的长周期成分丰富的多；两条长周期地震波的高频成分远远少于两条普通地震波；在小震时，古建筑木构架对长周期地震动的动力响应值与普通地震动相差不大，而在中震和大震时，对长周期地震动的动力响应值要远远高于普通地震动；大震（400gal）时木构架的减震效果比中震（220gal）、小震（110gal）时的减震效果要好。

Abstract

In the present research fields of ancient building, the seismic analysis of timber structure is most under the action of common seismic, but the dynamic research of timber structure under the action of long-period seismic is relatively few. Therefore, it mainly chooses two typical long-period seismic waves and common seismic waves, and takes dynamic research on the whole structure under the action of the two waves. Research shows that the chi-chi and Loma-Prieta waves are much more abundant in long cycle parts than that of the El-Centro and LAN Zhou waves; The high frequency components of the two long-period seismic waves are far less than two common seismic waves; In minor earthquake, dynamic response value of the structure under long-period and common seismic is probably the same, while in the moderate earthquake and major earthquake, the dynamic response value of long-period seismic is much higher than that of common seismic; The shock absorption effect of semi-rigid connection Sun-Mao in major earthquake (400gal) is better than that in moderate earthquake (220gal)and minor earthquake (110gal).
