摘要:
文中提出了一种带翼缘双折型钢板剪力键，旨在获得较好的承载力与变形能力；共设计6个试件，采用推出试验方法，研究该剪力键的破坏模式、受力性能、不同灌浆料以及贯穿钢筋的影响规律等；结果发现：该剪力键约束下，混凝土板开裂区域以剪力键为中心呈梯形分布，开裂面积达到1/2板面以上，显著高于栓钉连接形式；剪力键整体发生变形，其中孔外侧腹板屈曲明显。该剪力键滑移后，刚度衰减较小，承载力增长较快；与栓钉相比，普通混凝土叠合板剪力键的承载力提高50%以上，采用高强灌浆料后可提高1倍以上；同时，该剪力键在承载力达到峰值后，刚度及强度下降缓慢，表现出较好的变形能力。最后，基于双折型钢板剪力键破坏机理，建立简化力学模型，并提出承载力实用计算方法，与试验结果吻合较好。
Abstract:
In this paper,a double-folded steel plate shear key with flange was proposed to obtain better bearing capacity and deformation capacity. A total of 6 specimens were designed and the push-out test method was adopted to study the failure mode,mechanical performance,influence law of different grouting materials and penetrating reinforcement of the shear key.The results show that:under the constraint of this shear connector,the cracking area of the concrete slab is distributed in trapezoidal form with shear key as the center. The cracking area reaches more than 1/2 of the concrete slab,which is significantly higher than the type of bolted joint.The shear key is deformed as a whole,and the buckling of the pore lateral web is obvious.After sliding,the stiffness attenuation is small and the bearing capacity can be improved continuously.Compared with the bolt,the bearing capacity of the shear key of the composite slab of ordinary concrete can be increased by more than 50%,and it can be increased by more than one time after using the high-strength grouting material. After the bearing capacity reaches the peak,the stiffness and strength of the shear piece decrease slowly,showing better deformation capacity. Finally,a simplified mechanical model is established based on the failure mechanism of shear key of double-folded steel plate,and a practical calculation method of bearing capacity is proposed,which is in good agreement with the test results.
