METHOD OF NONLINEAR ANALYSIS FOR FUNDAMENTAL FRAME STRUCTURES IN MULTI-RIBBED WALL
Through the test of the fundamental infill frame structures in concrete multi-fibbed wall,the results indicate that the infill tends to partially separate from the bounding frame as the load increase. All specimens develop a distinct compression strut mechanism and eventually lead to comer masonry crushing and inelastic hinges in the frame members. Consider of the inelastic hinges at any location of the ribbed-beam/column, based on the three-nodded Euler beam-column element, the ribbed-beam/column stiffness matrix equation of the element is derived by employing specially tailored shape functions even when the element is under a linearly distributed transverse load. For the finite element analyses of the fundamental infill frame structures in concrete multi-ribbed wall, an equivalent strut model is established. The area of the equivalent diagonal strut in the fundamental infill frame structures in concrete multi-ribbed wall were determined by the tests. Meanwhile based on the elasto-plastic damage theory, assuming an isotropic damage evolution due to compression, the tangential stiffness relation can be arrived. So the model of the fundamental infill frame structures in concrete multi-ribbed wall was completely found.
