摘要
恢复力模型是描述往复荷载作用下钢筋混凝土结构弹塑性性能的基本要素,对钢筋混凝土结构抗震性能和计算机模拟有十分重要的意义.简要评述多年来国内外钢筋混凝土压弯构件恢复力模型的研究成果,分析了各种平面恢复力模型和空间恢复力模型的优缺点和存在的主要问题,介绍了恢复力模型的新发展,提出恢复力模型发展的研究建议.
Restoring force models describe fundamental principle of elastic-plasticity performance of structure during reciprocating load. So they are significant for earthquake-resistance performance of reinforced concrete structure and computer simulation. This paper expounds the research on restoring force models of R/C compression-flexure members at home and abroad. It analyzes the advantages and disadvantages of various kinds of restoring force models and introduces the new development of restoring force models. In conclusion, it puts forward some suggestions to develop and research on restoring force models.
