东胜网球馆为体育公共建筑,主体结构由十榀异形直立拱式刚架和两榀分别向外倾斜15°和10°的斜向异形拱式刚架组成。拱式刚架采用实腹式开圆孔H型钢截面,拱式刚架之间布置系杆与交叉支撑,与拱式刚架共同构成稳定的结构体系。主体结构的跨度为47m,大跨度开圆孔H型钢拱式刚架的设计是本工程设计的难点和关键点。对主体结构进行了整体分析和设计,并利用通用商业软件ANSYS对开圆孔拱式刚架的稳定性进行了分析,旨在探明拱式刚架结构的受力特点和设计要点。
Dongsheng Tennis Hall is a public sports building. The main structure consists of 10 arch-shaped upright arch frames and two diagonal arch-shaped arch frames inclined outward by 15 ° and 10 ° respectively. The arched rigid frame adopts the real abdominal open H section steel section, the tie bars and cross supports arranged between the arched rigid frames, and the arched rigid frame together form a stable structural system. The span of the main structure is 47m. The design of long-span open H-section steel arched rigid frame is the key and difficult point of this project design. The main structure of the whole analysis and design, and the use of common commercial software ANSYS analysis of the stability of the open-arch arched rigid frame to explore the arch-type rigid frame structure of the force characteristics and design points.
