Abstract

The invention relates to the technical field of building test devices. The invention particularly relates to a civil engineering structure anti-seismic test device. The device comprises a bottom plate, a first side plate and a second side plate are arranged on the side face of the bottom plate. The first side plate and the second side plate are perpendicular to each other. Excitation motors are arranged on the inner side faces of the first side plate and the second side plate. A cam is arranged on an output shaft of the excitation motor; the excitation motor is arranged on the fixed plate; twosliding rods are arranged on the fixing plate, two sliding holes are formed in each of the first side plate and the second side plate, the sliding rods penetrate through the sliding holes, a threadedhole is formed below the position between the two sliding holes, a screw rod is connected into the threaded hole in a threaded mode, the inner end of the screw rod is connected with the fixing plate,and a longitudinal wave generating plate is welded to the upper ends of the stand columns together; according to the device, vertical longitudinal waves and horizontal transverse waves can be generated for simulating the earthquake state, the simulated longitudinal waves are closer to the earthquake state, and the accuracy of the earthquake resistance test is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of building test devices, in particular to an anti-seismic test device for civil engineering structures. Background technique [0002] In large-scale civil engineering such as housing and bridge design, after the design drawings are completed, models are often made to verify the feasibility of the design scheme and drawings. After the model is completed, various simulation tests are required to To ensure the stability and reliability of the structure, the seismic test is an indispensable one among many tests. Among them, the earthquake resistance of civil engineering structures is mainly to simulate earthquakes, which are mainly divided into longitudinal waves and shear waves. First, the propagation direction of the longitudinal wave is parallel to the vibration direction, causing the building to vibrate up and down (refer to the attached Figure 8 ), then when a shear wave occurs, the propagation direction...
