城市绿地系统社会服务功能及其评价研究综述

城市绿地系统社会服务功能所具有的重要价值已在世界范围内引起了人们的普遍关注,有关城市绿地系统社会服务功能及其评价的研究也取得了较大的进展。但通过文献综述发现,这些研究对城市绿地系统社会服务功能与城市绿地的规划、建设、保护和管理之间的相互关系探究极少且深度不够,使得这些研究的实践意义不大。而在有关城市绿地系统社会服务功能评价的研究上,也存在着诸如评价指标少且未形成体系、研究范围较窄、研究的深度和广度不够等不足,以致不能真实、综合地反映出城市绿地系统多元的社会服务功能。为此,为了全面、客观地反映出城市绿地系统社会服务功能所具有的价值,应坚持综合性、层次性、独立性,可操作性、易获得性等原则,并构建定性与定量相结合的指标体系。

Progressive Collapse Analysis (PCA) is the base of quantitative assessment of progressive collapse-resisting capacity and progressive collapse-resisting design. There has been heightened interest among researchers of civil engineering in PCA. PCA of planar RC frame is carried on by vertical nonlinear dynamic analysis based on alternate load path method.

Two cases of removal of elements are analyzed, removal of columns at different stories on the same axes one by one and removal of all columns on the same axes at the same time. According to analysis of the effect of failure duration on structural progressive collapse, it is showed that the response of remaining structure is highly sensitive to failure duration of elements. The results indicate that vertical nonlinear dynamic analysis is an efficient method of progressive collapse-resisting design and progressive collapse-resisting capacity analysis.
