In order to improve the seismic bearing capacity of prefabricated concrete frame structure system,it is necessary to carry out quantitative test on the bearing capacity. A method for testing the seismic bearing capacity of an assembled concrete frame structure system based on linear evaluation of elastic modulus load stress is proposed. A constraint parameter model for seismic bearing capacity testing of fabricated concrete frame structure system is constructed. The stress yield response is evaluated with the method of force parameter estimation,and the seismic dynamic bearing capacity of the assembled concrete frame structure system is tested. The yield stress push-over response control method is used for the automatic loading and adaptive control of the seismic bearing capacity of the prefabricated concrete frame structure system,and the seismic and tensile capacity of the concrete frame structure system is tested. The optimum estimation of seismic bearing capacity parameters of concrete frame structure system is realized. The test results show that the accuracy of seismic bearing capacity test of prefabricated concrete frame structure system by this method is high and the seismic capacity of building body is improved.
