简述框架结构的特点及其抗震设计要点
摘 要
框架结构作为一种常用的结构形式，具有空间分隔灵活，自重轻，节省材料的优点，利于安排需要较大空间的建筑结构。这篇论文简述框架结构的抗震设计中注意的要点。抗震是结构设计中不可避免的，一个好的结构必须要有良好的抗震能力。普通房屋一般只需要考虑水平地震作用，用底部剪力法就可以算出其地震作用力的大小；8度和9度时的大跨结构、长悬臂结构、烟囱和类似的高耸结构则需要考虑竖向地震的作用，对竖向荷载进行折算，便能用水平地震的计算方法计算出竖向地震的作用。根据框架结构的特点以及其所在地区的抗震设防烈度可以确定出框架结构的抗震设防等级，并以此对其作出抗震验算，和构造措施的建设。至此便可完成对框架结构的初步抗震设计。

Abstract
As a common structural form, frame structure has the advantages of flexible space separation, light weight, and material saving. In this paper, the main points in seismic design of frame structure are briefly described. Aseismic design is inevitable in structural design. A good structure must have good seismic capacity. Ordinary buildings generally only need to consider the horizontal earthquake action, and can calculate the large span structure and long cantilever structure when the earthquake force is 8 degrees and 9 degrees by using the bottom shear method. Chimneys and similar tall structures need to consider the effect of vertical earthquakes. According to the characteristics of the frame structure and the intensity of the seismic fortification in the region, the seismic fortification grade of the frame structure can be determined, and the aseismic verification calculation can be made on the basis of the calculation of the earthquake resistance of the frame structure. Thus the preliminary seismic design of frame structure can be completed..
Key words : earthquake resistance; bottom shear method; vertical earthquake; horizontal earthquake; structural measures
