Seismic zonation maps against collapse of structuresin Sichuan and adjacent region

This paper analyzed the influence of different zonation methods through a numerical experiment. By taking into consideration not only the inheritance and continuity of previous versions of seismic zonation maps but also the joint of updated seismic design provision, the authors propose a set of criteria and methodologies for compiling the seismic zonation maps against collapse of structures based on the features of geological background, seismicity, K2 value and Delta;Tg distribution in Sichuan and adjacent region. Then the seismic zonation maps against collapse of structures for Sichuan and adjacent regions has been compiled.
