摘要

摘要: 由于大跨空间结构具有受力性能合理、轻质高强、结构形式美观等优点，在许多体育馆、展览馆、大会堂等建筑中被广泛使用。大连梭鱼湾足球场作为一个大型民用建筑，结构形式是平面为四心圆的索桁架结构，上弦索体斜交，下弦索体呈放射状，相比常规的轮辐式索桁架结构，该体系具有更强的面内刚度和整体抗扭能力。因为其结构形式复杂，下环索需要固定8道拉索和其他下弦径向索构件。为了满足该使用需求，设计了一种直径125 mm、带有6个高强螺栓的贴板压合型索夹节点。对设计的索夹节点开展2项试验，分别研究该节点张拉拉索时高强螺栓的紧固力损失情况和顶推索夹时该节点的抗滑移极限承载能力。首先组装索夹节点，静置24 h后再分三级张拉拉索至破断荷载的50%，再顶推索夹，直至索夹产生大幅度滑动。整个过程实时监测高强螺栓的紧固力变化、拉索直径变化和顶推阶段索夹位移变化。研究结果表明：高强螺栓受时间效应损失11%的紧固力；在第二步张拉拉索时，高强螺栓紧固力受拉索直径变小一共损失了17.8%的紧固力；第三步顶推索夹时，根据得到的位移-顶推力曲线，以曲线第一个拐点为抗滑移承载力极限值，得到该索夹节点的抗滑移承载力值为500 kN，代入抗滑移承载力计算公式得到索夹孔道与索体间的摩擦系数为0.165。试验得到的高强螺栓拧紧力矩值和抗滑移承载力值可以作为贴板压合型索夹节点的设计依据，为现场安装监测和施工提供坚实的理论基础。

Abstract: Due to the advantages of reasonable stress performance， light weight， high strength， and beautiful structural form， long-span space structures have been widely used in many stadiums， exhibition halls， assembly halls， and other buildings. As a large-scale civil building， Dalian Suoyuwan Football Stadium features a cable-truss structure with a four-center circle in plan. Its upper chords are obliquely crossed， while the lower chords follow a radial layout. Compared with conventional spoke-type cable-truss structures， the football stadium system demonstrates improved in-plane stiffness and overall torsional resistance. Because of its complex structure， the lower loop cable needs to fix 8 cables and other lower-chord radial cable members. To meet the requirements， a 125-mm-diameter plate press-fit cable clamp joint with six high-strength bolts was designed. Two experimental studies were carried out on the designed cable clamp joint. The paper investigated the tightening force loss of high-strength bolts during cable tensioning and the ultimate anti-slip capacity of the joint under cable clamp jacking conditions. Firstly， the cable clamp joint was assembled and left undisturbed for 24 hours. Then， the cable was tensioned in three stages up to 50% of its breaking load， followed by the cable clamp jacking until significant sliding occurred. The entire process was monitored in real time for high-strength bolt tightening force changes， cable diameter changes， and cable clamp displacement changes. The results showed that the tightening force of high-strength bolts was lost by 11% due to the time effect. The high-strength bolts experienced a 17.8% tightening force loss due to the reduction of the diameter of the tension cable when the cable was tensioned in the second step. During the third-step cable clamp jacking， the first inflection point of the displacement-jacking force curve was taken as the limit value of anti-slip capacity， and the anti-slip capacity value of the cable clamp joint was determined as 500 kN. The friction coefficient between the cable clamp channel and the cable body was 0.165 by introduing the anti-slip capacity formula. The tightening torque value and anti-slip capacity value of high-strength bolts obtained by the test can be used as the design basis for plate press-fit cable clamp joints， providing a solid theoretical basis for on-site installation monitoring and construction.
