［摘要］棗莊體育中心體育場屋蓋結(jié)構(gòu)為自平衡結(jié)構(gòu)體系，內(nèi)環(huán)采用索桁架體系，由上內(nèi)環(huán)、下內(nèi)環(huán)、飛桿和斜拉索組成，其中內(nèi)環(huán)斜索為單斜式布置，可能出現(xiàn)較大不平衡力。因此，有必要了解索夾受力性能，確保節(jié)點(diǎn)乃至整體結(jié)構(gòu)的安全性。在實(shí)驗(yàn)室條件下復(fù)現(xiàn)了索夾的實(shí)際結(jié)構(gòu)工作狀態(tài)，并進(jìn)行了索夾抗滑移性能測試，試驗(yàn)結(jié)果表明索夾設(shè)計(jì)能夠確保索夾節(jié)點(diǎn)結(jié)構(gòu)安全。

Abstract:The roof structure of Zaozhuang Sports Centre Stadium is a self-balanced structural system, and the inner ring structure adopts cable truss system, which consists of upper inner ring, lower inner ring, flying rod and inclined tensile cable. The inner ring inclined cable is in monoclinic-typed layout, which may appear large unbalanced force. Therefore, it is necessary to understand the mechanical behaviour of the cable clamp to ensure the safety of the joints and even the whole structure. Under the laboratory conditions, the working state of the actual structure of the cable clamp was reproduced, and the anti-sliding performance of the cable clamp was tested. The test results show that the design of the cable clamp can ensure the safety of the cable clamp joint structure.
Keywords:full tensile structure; cable clamp; anti-sliding; full-lock cable
