| The new composite wall structure researched by the studying team is a new, ecology, energy-saving assembled monolithic structure with good seismic performance, which adapts to China's national conditions and meets the wall material innovation and energy efficiency requirements for the building. The new composite wall structure uses various materials and components nesting each other, which makes the entities calculation model extremely complicated, therefore, it is necessary to present the simplified calculation model of the structure. Based on previous study and the calculation theory of modern high-rise structure,the simplified models of new composite wall structure in elastic stage and elastic-plastic stage are presented. The main research work and results are as follows:1,Based on previous study, the simplified numerical model—the frame-elastic composite panel combined model of new composite wall structure in elastic stage is presented, which is used to calculate the internal force and deformation of new composite wall structure during the elastic stage. According to the previous results of shaking table test on a 1/10 scaled model, the frame-elastic composite panel combined model is employed to perform the time-history analysis, therefore, the validity of the model is verified. Theoretical researches and experimental analysis show that it is not only supported by theory but also useful for practice to adopt the frame-elastic composite panel combined model as the numerical model in elastic stage. 2,Based on previous study and the calculation theory of modern high-rise structure, the simplified analytical model-the frame-composite wall model of new composite wall structure in elastic stage is presented. The comparative analysis of simplified numerical model and analytical model in practical engineering are carried out to verify the rationality of analytical model. The results showed that it is more reasonable to take the frame-composite wall model as the simplified analytical model in elastic stage,which provides a more simplified and practical hand-calculation method for practical engineering.3,Based on the analysis and the respective roles of the composite wall and fringe frame, the rigid frame-whole bracing model of new composite wall structure in elastic-plastic stage is presented to calculate the elastic-plastic calculation of structure. Based on the previous results of 1/10 ratio of shaking table test, the rigid frame-whole bracing mode is employed to perform the time-history analysis, therefore, the validity of the model is verified. Theoretical researches and experimental analysis show that the rigid frame-whole bracing mode giving consideration to accuracy and efficiency is applicable to structural elastic-plastic time-history analysis. |
