摘要
通过对汶川、唐山及云南等地震中典型的简支梁桥、连续梁桥、连续刚构桥和拱桥震害分析发现,相同桥梁体系的震害有许多共同特征,不同桥梁体系的抗震性能差异很大。本文结合数值分析,讨论了简支梁桥、连续梁桥、连续刚构桥和拱桥在各种条件下的抗震性能优劣,提出了地震区直线桥梁合理抗震体系的选择方法。
Damages of simple beam bridge,continuous beam bridge,continuous rigid frame bridge and arch bridge in Wenchuan,Tangshan and Yunnan earthquakes etc are analyzed.Many common features of the damage to the same bridge system and different seismic performance of various bridge systems are found.Seismic performance under different conditions for the simply supported bridge,continuous beam bridge,continuous rigid frame bridge and arch bridge are discussed.Reasonable seismic system selection for the straight line bridge in seismic zone are proposed.
