Abstract

The invention discloses a modular experimental device for civil engineering structure dynamic and static tests, which comprises an experimental workbench, an experimental structure module and a data acquisition and analysis system, and is characterized in that the experimental structure module is mounted on the experimental workbench through a spherical support, and a vibration device is arranged on the experimental workbench; the vibration device is detachably connected to the test structure module, a test trolley is placed on the test workbench, a loading groove is formed in the upper end of the test trolley, a power traction mechanism capable of driving the test trolley to move left and right is arranged on the test workbench, and a plurality of movable hooks are arranged at the lower end of the test structure module. The experiment workbench and the test structure module are both provided with various detection elements, and the detection elements are all electrically connected to the data acquisition and analysis system. Structural static loading test, dynamic loading test, bridge floor transverse coefficient test and moving load test can be carried out on the test structure module, simulation experiments with different requirements are met, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of construction experiment equipment, in particular to a modular experiment device for dynamic and static testing of civil engineering structures. Background technique [0002] With the progress of society, people travel more and more conveniently, and bridges play an irreplaceable role in providing convenience for people. After the design of the bridge structure is completed, it is necessary to make a model to carry out simulation experiments to simulate the deformation and damage of the structure under the attack of the external load in the natural environment, so as to evaluate the bearing capacity and anti-seismic effect of the structure, which is convenient Better optimization and improvement, which is also the process that students need to learn and experiment, but the existing experimental device has a simple structure, cannot carry out simulation experiments for different needs, and has poor applicab...
