1.设计地震是对建筑场地,用于进行结构物动态分析,预估最大地震地面运动合理衰减到厂址地区的,与震级、震中距和厂址条件密切相关的峰值加速度、峰值速度和峰值位移等的一个综合指标。它是当代在工程建设中保证建筑物结构安全、投资经济节约的重要前提。2.研究设计地震必须从研究断层运动开
1. Designing Earthquake is a building site for dynamic analysis of structures and estimating the maximum attenuation of seismic ground motion reasonably to the site of the site. Peak accelerations, peak velocities and peak displacements that are closely related to the magnitude, epicentral distance and site conditions A composite indicator It is an important prerequisite for ensuring the structural safety of buildings and saving the economy of investment in the current construction of the project. 2. Research Design Earthquakes must be opened from the study of the fault movement
