(北京市市政工程研究院,北京100037)[摘要] 在近期頻繁的地震地質(zhì)災(zāi)害面前,地震災(zāi)害對建筑物破壞所引起的人員傷亡已經(jīng)得到全社會的關(guān)注和重視。面對眾多存在隱患的建筑物,抗震鑒定工作的重要性和必要性已經(jīng)愈來愈突顯出來。建筑的結(jié)構(gòu)類型、建造年代、使用維護(hù)情況、施工質(zhì)量等情況的不同,抗震能力也有較大不同。在抗震鑒定實際工作中,由于現(xiàn)場檢測、鑒定條件所限,規(guī)范中鑒定程序規(guī)定的每一條要求往往不都是顯而易見的,比如砌體結(jié)構(gòu)的構(gòu)造柱、圈梁配置;樓、屋蓋的支撐長度等等,這就需要鑒定人員通過結(jié)構(gòu)的綜合抗震能力分析確定鑒定結(jié)果。從結(jié)構(gòu)綜合抗震能力的角度審視既有房屋的抗震鑒定,把握綜合抗震能力這個著眼點,采用逐級鑒定方法,根據(jù)建筑結(jié)構(gòu)的本身特點,可提高抗震鑒定的效率和可靠性。

( Beijing Municipal Engineering Research Institute, Beijing 100037, China)Abstract: Geological disasters such as earthquakes frequently occurred recently. The damage of buildings caused by earthquakes has been paid attention of the whole society. Faced the buildings with seismic risks, the importance and necessity of seismic appraisal was mcreasingly prominent. Because of different structure types, building ages, use and maintenance conditions, construction quality, different buildings have quite different seisnuc ability. In practical seisnuc appraisal work, because limited conditions of on-site detection or seismic appraisal, not every requirements in specifications are obviously, such as constructional columns and ring beams in masonry structural; the length of the roof supported, etc. The engineers determine the seismic capacity of existing buildings by way of structural general seismic capacity analysis. The general seismic capacity of existing buildings was inspected from the perspective of seismic appraisal, and the integrated seismic capacity was grasped. Based on characteristics of the building structure itself and using step by step identification method, the efficiency and reliability of seismic appraisal can be improved.
Keywords: general seisnuc capacity; seismic appraisal
