Comparative Study of Seismic Analysis for Reinforced Concrete Frame Infilled with Masonry and Shape Memory Alloy Wire

A.A. Adedeji and S.P. Ige

Abstract: Finite Element Method (FEM) analysis was implemented to investigate and compare the performance of a reinforced concrete bare frame, infilled with and without straw bale wall and Shape Memory Alloy (SMA) diagonal wires, subjected to seismic loads and earthquake ground excitations. Equivalent lateral force (static), response spectrum and time history method of seismic analysis were embarked upon to determine the frame capacities, investigate their failure mechanisms and compare their residual and inter storey drift with one another. Also their respective maximum storey displacements have been graphically presented alongside with moments and shear forces. It has been observed from this analysis that under the lateral force, bare frame and straw bale wall infill experienced Maximum Top Storey Displacements (MTSD) of 55.63 and 55.61 mm, respectively. The maximum storey displacement was reduced to 11.19 mm with the application SMA as a concentrically brace members which give 79.8% reduction in the maximum storey displacement. Under UBC97 spectrum, the maximum top storey displacement reduced by 47.3, 52.4 and 73.5% for straw bale wall, SMA brace frame and SMA-straw bale frames respectively. Under Elcentro earthquake ground excitation, the maximum top storey displacement reduced by 0.02, 7.5 and 78.9% for straw bale wall, SMA brace frame and SMA-straw bale frames, respectively. From the results of the analysis, the displacement of the frame is drastically reduced by a concentric application of SMA wires in the frame. The computed force-deformation response used to assess the overall structural damage and its distribution was found to have a sufficient degree of accuracy.
