THE STRESS AND STRAIN ANALYSIS AND TEST STUDY UNDER HORIZONTAL LOADS FOR HOLLOW FLOOR OF CONCRETE

摘要

The frame structure of concrete hollow floor is one kind of new structure which the appearance nearly 10 years. Because of the section performance is different from the concrete hollow floor and concrete solid floorboard, under the horizontal loads the structure stress characteristic is difference from the hollow floor and the solid floor. By use of the finite element software analysis, the stress analysis is researched under horizontal loads in concrete hollow floor. Through the test of 1/3 scale model multi-floor concrete hollow floor and the testing result compare with the calculating analysis result, it is put forward that the calculating formula of equivalent beam width. It is researched by this model test that the anti-seismic characteristics, for example the hysteresis curve and the stiffness degradation and the ductile behavior of concrete hollow floor frame. The research results can provide the reference for the concrete hollow floor design.
