Research On Restoring Force Model Of Multi-ribbed Composite Wall

Multi-ribbed composite wall structure is a new type of energy consumption structure damping system, with good development prospects and seismic capacity. Multi-ribbed composite wall as its main force elements and in multi-storey high-rise housing construction in the theory and application Research has made an important initial result. Research on the resilience of the wall of a resumption of the model, the guiding design, promote multi-ribbed wall structure, the relevant protocols are developed is of important significance. Therefore, this article focused on several areas to do the work.1.14 wall panels in the experimental study, based on the multi-ribbed composite wall damage patterns, hysteretic curve, the skeleton curve, displacement ductility, energy capacity, stiffness degradation, the impact of seismic intensity attenuation of the important areas a comprehensive analysis.2. According to the bearing capacity, stiffness and failure mode and deformation properties of multi-ribbed composite wall, put forward a four-linear restoring force model, and determine the resumption of the model in various characteristics of the formula for calculating the points, using statistical analysis software-SPSS for Windows test data regression analysis, giving stiffness degradation of the Logarithmic function models.3. Based on the use of macro model of non-linear finite element analysis program IDARC simulated multi-ribbed wall of the hysteretic curve, the results agree well with the experimental data.4. Reference pre-vibration shaking table test results, doing the multi-ribbed structure of the wall Elastoplastic earthquake response test, and shaking table test results were compared, and an actual structure of the earthquake response analysis.
