|Performance of precast concrete load-bearing panel structures in regions of low to moderate seismicity
|Wilson, J.L., Robinson, A.J., Balendra, T. (2008-07). Performance of precast concrete load-bearing panel structures in regions of low to moderate seismicity. Engineering Structures 30 (7) : 1831-1841. ScholarBank@NUS Repository. https://doi.org/10.1016/j.engstruct.2007.12.008
|The performance of jointed precast concrete load-bearing panel structures is evaluated using the capacity spectrum method for Australian seismic conditions which is typical of low to moderate seismicity regions. The critical element in the load path is the connection between the floor slab and the wall panel, and sub-assemblage tests are carried out in order to calibrate a finite element model for typical load displacement characteristics. The calibrated model is used to evaluate the performance of a full scale structure using the demand spectra given in the Australian code for various soil conditions. It is found that the seismic performance is inadequate under deep soil and very soft soil conditions for the structure detailed with deep embedment connections. In comparison for the structure with shallow embedment connections, local damage to the concrete topping slab would be expected for ground motions on shallow soil or very soft soil, but overall structural stability would be maintained for the ultimate limit state event.
