| 摘 要： | 结构竖向不规则布置是导致结构地震损伤破坏的主要原因之一.介绍了建筑结构沿竖向的强度、刚度和质量不规则布置的定义、不规则的主要内容及其在地震作用下损伤破坏的特点;总结回归了钢筋混凝土竖向不规则结构地震反应需求的研究现状以及国际上典型的结构设计规范中结构竖向不规则条款的限定.针对竖向不规则结构目前的研究现状,提出了今后值得进一步加强研究的方向. |
| 关 键 词： | 竖向不规则结构 抗震性能 地震反应需求 建筑抗震设计规范 |

| Abstract: | Vertical irregularities of buildings are the major factor which initiates or aggravates the damage failure of structures.In order to improve our understanding of the seismic conceptual design of structures with vertical irregularities,this paper presents the definition of the irregularities of buildings along vertical direction,such as stiffness irregularity,strength irregularity and mass irregularity,the main contents and the damage characteristics under the earthquake actions.The recent research progress ... |
| Keywords: | vertical irregularities structures seismic performance earthquake response demand seismic code for building |
