摘要
以山东临沂翔宇旅游观光打卡地的拱门、天廊工程为背景,对大矢跨比交叉钢拱-百米天廊复合结构体系进行了分析设计.介绍了其工程概况,论述了该体系的结构特点,阐述了结构体系中天廊、拱门、天桥设计的核心内容,提出了大矢跨比交叉钢拱支承的结构形式,指出了天廊采用弱连接的设计特点,明确了天廊和天桥采用TMD装置对行走荷载激励下的振动进行控制.利用AN-SYS有限元软件对大矢跨比交叉钢拱-百米天廊复合结构的受力特性进行分析,结果表明结构性能安全可靠,各项指标符合设计规范要求.最后提出了该体系需要进一步研究的关键技术课题.
Abstract
Taking the arch and corridor project of Xiangyu tourist and sightseeing place in Linyi,Shandong province as the background,the composite structure system of large rise-span ratio cross steel arch and hec-tometre corridor was analyzed and designed.The overview of the project was introduced,and the structural design features of the system were discussed.The core content of the design of corridor,arch and pedestri-an bridge in the structural system was expounded.The structural form of cross steel arch support with large rise-span ratio was presented.The design characteristics of the corridor with weak connections was pointed out.It was defined that TMD device was used to control the vibration of the corridor and pedestrian bridge under the excitation of walking load.The ANSYS finite element software was used to analyze the mechani-cal characteristics of the composite structure.The results showed that the structural performance was safe and reliable,and the indexes conformed to the design specifications.The key technical issues needing fur-ther study were put forward.
