| Multi-ribbed slab with light frame structure is a new structural system. Important progress has been made inprevious study, but mode analysis and non-linear earthquake response study on the new structure remain blank andunsolved. The thesis is devoted to these two problems and to aseismic design based on damage property. Such workhas been done as follows:1. Stress-stain relationship of silicate brick was proposed. Solid element kinematic hardening model and William-Wamke 5-parameter failure mode were adopted in the non-linear FEM analysis on the multi-ribbed slab wall. Silicate brick's, concrete rib beam and rib column's cracking and crushing law was considered so as to reflect the whole failure process of the slab. Tests were carried out to check the reasonableness of the computation model. Numerical analyses on such factors as vertical load, horizontal load were done. And advice on the design and detailing of the slab were given.2. According to the slab's bearing capacity, rigidness, failure mode and deformation property, the thesis suggested four-linear resilience model for the slab and computation formula for the characteristic points' values in the model. Based on large amounts of numerical analysis, bi-parameter damage model of the slab was proposed, damage factors' value was defined and damage analysis was carried out on some tested slabs, the reliability of the damage model were validated.3. Shaking table test on 1/10 building model was carried out. Through hammer blow test and sine wave swept test, the model's parameters were acquired. By earthquake wave excitation, the model's earthquake response, failure traits and aseismic property were gained. Through ratio conversion, prototype's mode parameters and aseismic capability were studied.4. Simplified analysis model was established for multi-ribbed slab with light frame structure at elastic stage. Classical Timenshenko beam theory was employed in the study on analytic method of the mode. Three-dimensional beam element and three-dimensional shell element were used to establish three-dimensional model for the structure. Mode condensed technology was used to solve reliability problem of three-dimensional FEM mode.5. Three-dimensional computation model was adopted in the non-linear earthquake response of model in shaking table test and practical project so that analysis method of multi-ribbed slab with light frame structure's non-linear earthquake response was given. To match the prevailing codes, tests and computation examples discussed elastic angular displacement limit value under small earthquake and plastic angular displacement limit value under big earthquake respectively. 6. The idea of a seismic design based on property was introduced into the design method of the new structure.Correlational research achievement both at home and abroad were studied to establish shear-type damage model for the structure. To associate aseismic design idea that "no damage under light earthquake, reparable under medium degree earthquake and no collapse under intense earthquake" with design method based on damage property, the thesis adopted different damage limit values to control structural damages at different levels so that the designed structure can embody the substantial need of aseismic design based on damage property. Based on existing research conclusions, two methods calculating damage model's parameters were discussed in detail. They are time-history analysis method and simplified method. The originality of the thesis lies in:1) Establishment of restoring force model and damage model of multi-ribbed slab2) Shaking table test to study the mode of earthquake response of multi-ribbed slab with light frame structure 3) Proposal of analytic method and FEM method of the structure's mode, study on the reliability of the FEMmodel by mode condensed technology 4) Non-linear earthquake response analysis on test model and practical engineering by three-dimensional model,suggestion of inter-layer angular displacement value.5) Introduct...
