③ 摘要
在方空截面構(gòu)成的桁架的N型節(jié)點(diǎn)處很容易發(fā)生塌陷破壞。為了使桿件破壞先于節(jié)點(diǎn)破壞，一個很好的方法就是將桁架的弦桿灌漿來提高空弦桿的坍塌承載力。進(jìn)行了一個由灌漿方鋼管構(gòu)成的八個試樣的N節(jié)點(diǎn)的試驗?；趯υ囼灥难芯浚M(jìn)行了試件的幾何參數(shù)分析，套箍系數(shù)ξ的效應(yīng)、兩個腹桿g之間的間距和垂直腹桿的側(cè)向長度與基于試件性能的弦桿β的側(cè)向長度的比值通過依靠ANSYS程序進(jìn)行的模擬分析而被調(diào)查研究?；谠囼灲Y(jié)果和模擬分析，揭示了這種節(jié)點(diǎn)的力學(xué)性能和失效模式，預(yù)測相應(yīng)于不同失效模式的極限承載力的公式也被得出。根據(jù)一根弦桿的坍塌失效模式受壓N節(jié)點(diǎn)的極限承載力被計算出來；根據(jù)沖剪失效模式受拉N節(jié)點(diǎn)的極限承載力被計算出來；根據(jù)正剖截面的剪切失效模式，弦桿的極限承載力被計算出來

Cave—in failure is apt to occur in joints of trusses made of square hollow sections．In order to turn the failure mode into a strength failure mode of joint members，the idea is proposed that the chord of the truss is grouted to increase the cave—in beating capacity of a hollow tube chord．An experiment of eight specimens of N—joints made of grout—filled square steel tubes is performed．Based on the experimental study，the geometrical parameters of specimens are analyzed，and the effects of the confinement index ξ，the spacing between the two web members g and the ratio of side length of the vertical web member to that of the chord β on the behavior of specimens are investigated through simulation analysis by an ANSYS program. Based on the test results and simulation analysis，the mechanical properties and the failure modes of this kind of joints are analyzed and the formulate to predict the ultimate beating capacities corresponding to different failure modes are developed． The ultimate beating capacity of compressive N-joints is calculated in accordance with the cave—in failure mode of a chord member；the ultimate beating capacity of tension N-joints is calculated in accordance with the punching—
shear failure mode；the ultimate beating capacity of a chord member is calculated in accordance with the shear failure mode in normal sections．
