【摘要】 近年来,我国城市化进程加速推进,城市密集程度不断提高,但土地资源紧缺、环境污染等一系列“城市病”也日渐凸显。在此背景下,一种集住宅、办公和休闲娱乐等服务功能为一体的新型建筑——综合体建筑应运而生。然而,地震作用下综合体建筑功能失效会对周边乃至整个城市造成难以计量的经济损失以及重大社会影响。基于此,合理规划综合体建筑震后修复路径是实现此类结构震后功能需求的关键。在既有研究中,建筑震后多采取自下而上的修复路径,且修复方式未考虑震后功能需求。本文以大体量、多功能的综合体建筑为研究对象,提出了一种基于功能需求的综合体建筑震后修复路径优化方法。研究内容包括以下三个方面:（1）首先,采用故障树分析法对综合体建筑功能损失原因进行定性分析。对综合体建筑功能进行分析分解,定义各子功能区,采用地震易损性确定综合体建筑构件损伤状态,并确定构件功能损失情况;采用故障树分析法对综合体建筑内具有功能相关性的构件功能损失过程进行分析。（2）其次,明确综合体建筑构件修复逻辑关系,提出一种基于功能需求的综合体建筑震后修复路径优化方法。将《标准》和REDi ^TM建筑修复策略进行对比,确定了综合体建筑震后修复路径优化模型的目标;基于功能分区及《标准》相关规定,明确构件间的修复逻辑关系,搭建基于功能重要程度的修复网络图;提出一种基于功能需求的综合体建筑震后修复路径优化模型,采用遗传算法进行求解。（3）最后,将上述优化模型应用于大连北站交通枢纽综合体。该案例实现了综合体建筑震后修复路径优化过程,验证了优化方法的可行性。结果表明:该优化方法可有效缩短综合体建筑震后重要功能的修复时间以及建筑总修复时间,可为综合体建筑震后修复决策提供参考。更多还原

【Abstract】 In recent years,China’s urbanization process has accelerated,and the degree of urban density has been increasing,but a series of "urban diseases" such as shortage of land resources and environmental pollution have become increasingly prominent.In this context,a new type of building integrating residential,office and leisure and entertainment services-complex architecture came into being.However,the failure of complex buildings under the action of earthquakes can cause incalculable economic losses and significant social impacts on the surrounding area and even the entire city.Based on this,reasonable planning of the post-earthquake repair path of complex buildings is the key to realizing the post-earthquake functional requirements of such structures.In the existing studies,the bottom-up repair path of buildings after earthquakes is mostly adopted,and the repair methods do not consider the functional requirements after earthquakes.Taking large-scale and multi-functional complex buildings as the research object,this paper proposes a post-earthquake repair path optimization method for complex buildings based on functional requirements.The research includes the following three aspects:(1)Firstly,the fault tree analysis method is used to qualitatively analyze the causes of the loss of complex building functions.The function of the complex building was analyzed and decomposed,each sub-functional area was defined,and the damage status of the complex building components was determined by seismic vulnerability,and the functional loss of the components was determined.The fault tree analysis method is used to analyze the functional loss process of components with functional correlation in the complex building.(2)Secondly,the logical relationship of complex building component repair is clarified,and a post-earthquake repair path optimization method of complex building based on functional requirements is proposed.The standard and REDi TM building restoration strategies were compared to determine the objectives of the post-earthquake repair path optimization model of complex buildings.Based on the functional partition and the relevant provisions of the Standard,clarify the repair logical relationship between components,and build a repair network diagram based on the importance of the function;A post-earthquake repair path optimization model of complex buildings based on functional requirements is proposed,and genetic algorithm is used to solve it.(3)Finally,the above optimization model is applied to the transportation hub complex of Dalian North Railway Station.This case realizes the optimization process of post-earthquake repair path of complex building,and verifies the feasibility of the optimization method.The results show that the optimization method can effectively shorten the repair time of important functions and the total repair time of complex buildings after earthquake,and can improve the reference for post-earthquake repair decisions of complex buildings.更多还原
