Research On Seismic Behavior Of Energy-Saving Block & Invisible Multi-Ribbed Frame Walls

Along with reform and open to go deep into, as an important marking in the development middle class family society-residence construction develops fast. Energy–saving block & invisible multi-ribbed structure, as a new structural system, is very potential. But there is still a lot to be advanced research, complement in the development application process of new construction system.The paper, through the test study on seismic behaviour under low-cycle lateral loading and the factor analysis, studied rigidity, restoring force characteristic and oblique section bearing capacity of energy-saving block & invisible multi-ribbed wall. Finished work as following:Though seismic test of six 1/2-scaled model walls, the paper studied breakage form, bearing capacity, deformation and energy consume, questioned stagnant speciality and contrast analyzed all kinds of factors influenting rigidity. Test showed that under low-cycle lateral loading the damage process of model wall was according to the order of aerated block, interior frame, exterior frame, released energy classificately, had perfect energy consume and anti-collapse capacity.Considering the special structure of energy-saving block & invisible multi-ribbied wall, founding diphase body mechanical model of compound material, strengthening aerated block with rib beam and rib pillar by equivalent volume ratio of concrete and aerated block, the paper drew elastic compution constant and shear constant. Based on the things, the paper simplified isotropy compution model to wall, gave practical design formula of elastic modulus and shear modulus, provided necessary parameter for practical design formula of elastic rigidity. Finally the calculating results agree well with the experiment results.According to the bearing capacity, rigidity, failure mode and deformation capcacity, the paper put forward quadrilinear restoring force model of model wall. Through experiment data compare, the paper concluded the reduction factor of rigidity of other stage to elastic stage. Consulting the previous research, the paper suggested the calculation method of every characteristic parameter point in restoring force model.Based on seismic test under low-cycle lateral loading, the paper analyzed the factors which may influence oblique section bearing capacity of energy-saving block & invisible multi-ribbied wall and advised a practical design formula...
