This study proposes two types of U-bar joints: rectangular joints with stainless steel ties and T-shaped joints. The mechanical properties of four joint specimens subjected to combined bending and shear forces were studied experimentally and numerically. The T-shaped joint details effectively increased the cracking load and controlled the development of interface cracks. The bearing capacity of the four joint details were similar. Furthermore, a formula to estimate the bearing capacities of the T-shaped U-bar lap joint specimen is proposed, and its accuracy is verified.

弯曲与剪切联合荷载作用的预制桥面板之间的U型节点研究

这项研究提出了两种类型的U型杆接头：带不锈钢扎带的矩形接头和T形接头。实验和数值研究了四个联合弯曲和剪切力的联合试样的力学性能。T形接头的细节有效地增加了开裂负荷并控制了界面裂纹的发展。四个关节细节的承载能力相似。提出了估算T形U型搭接接头试样承载力的公式，并验证了其准确性。
