Reinforced Concrete Frame - Shear Wall Structure With Nonlinear Seismic Calculation Methods And Its Applications

This dissertation studies the imitation of artificial earthquake acceleration time-history, time-history analysis method and Push-over analysis method of reinforced concrete frame-wall structures. (1).In this paper, a construction function family satisfied all requirements is developed and exact solution of PSDF through their response is achieved by applying the construction function family. At last an artificial earthquake acceleration time-history is formed by the PSDF. It can be used as an input earthquake acceleration time-history of specified architectural field. (2).Bar element model with varied stiffness in different 5 regions and modified equivalent column element model are used to replace bar elements and wall elements of plane reinforced concrete frame-wall structures respectively. And then time-history analysis of reinforced concrete frame-wall structure is applied. (3).Some modifies have been made in the following four aspects: election of element model, election of structural shape vector, calculation of structural objective displacement and decision of horizontal load distribution pattern along the height. All these modifies want to improve the accuracy of Push-over analysis method and broaden the adaptive scope of it. Microcomputer-based programs of the imitation of artificial earthquake acceleration time-history, time-history analysis and Push-over analysis of plane reinforced concrete frame-wall structures are developed. The reliabilities of all these methods and the programs are demonstrated in a series of numerical examples.
