| Abstract | The advantages of precast concrete construction has been well recognized by entire profession who esteem the quality, cost and time effectiveness, functional versatility and post-earthquake revival besides the strength and adequacy of their designs. In recent years, the on-site prestressing of prefabricated structural modules has been addressed by many researchers under prominent research programs. Present study has been ventured to appraise the seismic behavior of frame-wall lateral load resisting precast systems integrated by hybrid connection methodology whereby fully debonded post-tensioning tendons provide the shear and flexural strength while embedded mild steel reinforcing bars serve as energy dissipators and additional strength source at inter-component zones. Such a configuration has been coined the hybrid frame-wall systems since the global behavior is highly dependent on the characteristics of utilized hybrid joints. Performance based evaluation of six prototypes including four framewall and two frames under high seismic risks makes up the framework of investigation. The prototypes have been designed for elastic range of response with application of code specified static lateral loads and the inelastic state of behavior as well as the performance levels (expected damage extents) are evaluated using a course of nonlinear static and inelastic response history analyses. The preliminary observations signify the viability and promising performance of hybrid frame-walls since the design level damage in terms of inter-story drifts and spalling of concrete at connection interfaces are satisfactorily limited. This becomes more appreciable considering the poor performance of alternative frames for which large local rotation demands trigger a propagating bar fracture mechanism which generates unacceptable drifts even at the design level of performance. The danger of shear slip at wall base due to assymetrical rotations as well as requirement of additional costs associated with the capacity design of exterior columns and mid hight panel gaps can be pointed out as considerable defficiencies indicating the neccessity of extensive investigations. |
