The invention is a bidirectional test loading device. The device comprises a lower plate, an upper plate, a spherical hinge, a standing column and a connecting end. In the loading test process, test pieces are mounted between the lower plate and the upper plate through bolts, are connected with the connecting end by the two actuators in two orthogonal directions, and are loaded. The device utilizes the test pieces as a part of a loading frame to form a stable stress state, so the test pieces undergo in-plane and out-of-plane bidirectional loading. The bidirectional test loading device is usedfor various structural members bearing bidirectional deformation in an actual earthquake, and has the advantages of easiness in processing, simplicity in installation, small system error and accuratetest result. 本发明为种双向试验加载装置，包含下板、上板、球铰、立柱和连接端。加载测试过程中，试验件通过螺栓安装在下板与上板之间，两个正交方向上通过两个作动器与连接端连接并加载。本装置利用试验件作为加载架的部分，形成稳定受力状态，使试验件同时经历平面内和平面外的双向加载。针对各类在实际地震中承受双向变形的结构构件，本发明可作为双向试验加载装置，加工容易、安装简便，系统误差较小、测试结果准确。
