摘要
随着现代社会经济、工业、文化、交通及体育事业的不断进步,建筑功能呈现多元化特点,现代建筑对内部大空间产生了较大需求,尤其对楼盖的跨度提出了更高要求。目前尚没有针对大跨度楼盖结构方面的系统梳理和总结,导致在实际工程设计中结构选型概念较为混乱,给实际工程设计带来不便,亟待对适用于大跨度楼盖的结构形式进行归纳梳理,并对现有研究现状进行总结,以便为工程实践提供参考。因此,系统梳理了大跨度楼盖的研究与应用现状,总结了6类适用于大跨度楼盖的结构体系:预应力混凝土楼盖、钢-混凝土组合楼盖、钢网架组合楼盖、空腹楼盖、弦支组合楼盖以及装配式楼盖,并对这6类结构体系在结构概念与形式、静动力性能、施工全过程分析以及人致振动规律及控制等方面的研究现状进行了归纳,同时详细介绍了每种楼盖结构的代表性工程。最后,探讨了大跨度楼盖结构体系面临的主要问题和发展方向,包括:适用于30 m以上跨度的楼盖结构形式较少,大跨度楼盖结构方面的试验数据匮乏,大跨度楼盖人致振动控制技术较为复杂等。对现有大跨度楼盖结构形式、研究现状及工程应用情况进行了较为系统、详细的梳理总结,具有一定工程参考价值。
With the continuous advancement of modern social economy,industry,culture,transportation,and sports,the functions of buildings have become increasingly diverse.Consequently,there is a growing demand for expansive internal spaces in contemporary architecture,particularly in terms of floor spans.However,there is currently a lack of systematic review and summary regarding longspan floor structures.This has led to confusion in selecting suitable structure during practical engineering design processes and has caused inconvenience to such designs.Therefore,it is crucial to summarize the appropriate structural forms for long-span floors and compile existing research status to provide valuable references for engineering practices.Thus,this paper systematically summarized the research and application status of long-span floors by categorizing them into six types:prestressed concrete floors,steel-concrete composite floors,steel grid composite floors,hollow floors,string-supported floors and prefabricated floors.The research status of these six types was further summarized based on their structural concepts and forms,static and dynamic performance evaluations,construc⁃tion process analysis as well as human-induced vibration laws and control measures.Additionally,representative projects pertaining to each type were elaborately introduced.Finally,this paper discussesd the main challenges faced by long-span floor structure systems along with their development directions.These included limited options for floor structures suitable for spans exceeding 30 meters,insufficient experimental data on long-span floor structures as well as complex human-induced vibration control technologies appli⁃cable to such structures.This paper provides a comprehensive summary of existing forms of long-span floor structures while also pre⁃senting their research status and engineering applications in detail,which has a certain value in engineering applications.
