[概要]“抗震”现在已然成为了建筑结构设计的焦点。就我国目前状况而言大多都是以小震设计为主的。但是，随着建筑师的奇思妙想，建筑造型越来越追求极致，导致超高超限建筑愈来愈多，结构设计愈来愈复杂，这对中震设计的要求也越来越多。目前工程界对于中震设计有两种方法，他们分别是中震弹性设计和中震不屈服设计。本文主要探讨在MIDAS/Gen中如何实现中震弹性设计。

Abstract: anti-seism has become the focus of the building structure design. In the present situation in China, it is mostly dominated by seismic design of small earthquake. However developing with the architect's fancy, architectural modeling is more and more pursuing of perfection, which causes structural design more and more complex and an increasing number of ultrahigh transfinite structures. This requires the seismic design more of moderate earthquake. At present ,there are two ways in the engineering for seismic design of moderate earthquake: elastic design for the moderate earthquake and unyielding in deismic design. this paper mainly discusses how to achieve elastic design of moderate earthquake in MIDAS/Gen.

Keyword: MIDAS/Gen; design of anti-seism; seismic design of moderate earthquake
