HYSTERESIS PERFORMANCE ANALYSIS OF REINFORCED CONCRETE THIN-WALLED PIERS WITH RECTANGULAR HOLLOW CROSS-SECTION UNDER BI-DIRECTIONAL LOW CYCLIC LOADING BASED ON FIBER BEAM-COLUMN ELEMENT
In this paper,the basic situation of bi-axial quasi-static testing of fourteen reinforced concrete thin-walled piers with hollow cross-section was firstly introduced.And then,the basic procedure to establish finite element model of the piers based fiber beam-column element was carried out.Finally,the analytic results including bidirectional hysteresis curves and skeleton curves were compared with the test ones.The main conclusions are listed as follows:(1) Analytical hysteresis curves and skeleton curves agree well with the test ones generally; (2) Calculating ultimate load is generally smaller than the test ones while the calculating ultimate deformation is a few bigger; (3) Nonlinear fmite element model established by nonlinear fiber beam-column element has a good prediction of nonlinear mechanical properties in action of bidirectional cyclic static loading and can be used further for parameter analysis.
