Abstract:The structure of the Puer Theatre for Nationality is complex and irregular in plane. The main procedures of structural arrangement, structural model and structural design were introduced. Based on PMSAP and ETABS programs, results of static analysis and earthquake response under frequent earthquake were compared. Contrast results of elastic analysis under medium earthquake, elasto-plastic static and dynamic analysis under rare earthquake were given. The necessity of elasto-plastic analysis for this asymmetric structure was pointed out.
Keywords:theatre; irregular structure; medium earthquake; elasto-plastic analysis; ETABS
