项目摘要
(1) Dynamic elastic-plastic FEM is used to analyze the seismic response damage of the existing reinforced concrete piers. The effect of the embedment length of reinforcement at the location of the bar-reduction sections and also vertical seismic motion are more focused(2) We have developed a database of damage to bridge structures using GIS and examined damage factors through a statistical analysis of bridge which have been heavily damaged during Hyogo-Ken Nanbu Earthquake.(3) Focussing on the Hanshin Expressway viaduct at Fukae section which has been destroyed by Hyogo-Ken Nanbu Earthquake, the authors have done this inverstigation with the aid of dynamic response earthquake analysis, using distinct Element Method.(4) This study intends to identify important aspects of the mechanisms that caused the collapse of some types of bridges supported by single-column bents, through a Finite Element analysis.
(1)采用动力弹塑性有限元法对既有钢筋混凝土桥墩的地震反应损伤进行了分析。(2)利用GIS技术建立了桥梁结构损伤数据库,并对兵库县南部地震中严重受损的桥梁进行了统计分析,研究了影响桥梁结构损伤的因素。(3)本文以坂神高速公路桥江段高架桥在兵库县南部地震中的破坏为研究对象,采用离散单元法进行了动力反应地震分析。(4)本研究旨在通过有限元分析,确定导致某些类型的单柱排架支撑的桥梁倒塌的机制的重要方面。
