摘要
建筑框架结构在爆破震动或自然地震激励下,会产生振动放大效应的动力响应特征,研究这一特征对框架结构的抗震设计具有重要的指导意义。本文采用物理相似模型试验的方法,以一栋6层的单跨钢筋混凝土结构建筑物为原型进行振动台模型试验,通过振动台水平和垂直方向的振动,改变振动波的频率和强度加载参数,模拟分析了不同振动荷载作用下,框架结构的振动放大效应特征。
Under the excitation of blasting vibration or natural earthquake,the dynamic response characteristics of building structures will produce vibration amplification effect.Research and analysis of the response characteristics of the building(structure)under the vibration effect have important practical significance.This article adopts the method of physical model test with a six floors reinforced concrete structures as a prototype for shaking table model test.Through the vibration of horizontal and vertical direction,change the frequency and strength parameters of the vibration wave,simulation the vibration of horizontal and vertical direction on the influence of frame structure under different conditions.
