前言近二十年来,人们对结构物弹塑性地震反应的研究,已引起很大的重视,电子计算机的日益广泛应用,又为这一课题的研究工作提供了方便的条件。目前研究范围多趋向于多层或高层建筑,而单层工业厂房尤其是钢筋混凝土排架的弹塑性地震反应的研究还较少。本文试图用比较简便的方法,计算单层厂房(铰接排架)的弹塑性地震反应问题;并 Foreword In the past two decades, people’s study on the elasto-plastic seismic response of structures has attracted great attention. The increasing application of electronic computers has provided convenient conditions for the research of this subject. At present, the scope of research tends to be multi-storey or high-rise buildings, while the study of elasto-plastic seismic response of single-story industrial plants, especially reinforced concrete bents, is still relatively rare. This paper attempts to calculate the elasto-plastic seismic response of a single-storey factory building (articulated and bent) using a relatively simple method;
