Reinforced concrete beam with pseudoelastic SMA hybrid with steel structure for seismic mitigation: A critical review of their prospective,influence factors,drawback and advantages

摘要

This paper presents a review paper of concrete beam reinforced with SMA hybrid with steel.Existing literature presented a number of analytical and experimental studies on the use of SMAs using pseudoplastic to be embedded in reinforced concrete beam for crack recovery.However,little research has been carried out on the use of pseudoelastic SMA as reinforcement as partial replacement in reinforced concrete beam.Hence the feasibility of pseudoelastic SMAs under austenitic temperature window and several components of RC building structures to exhibit stable superelastic under austenite crystallization were investigate.This paper is to review the feasibility study NiTi SMA as reinforcement rebar for seismic mitigation.This research investigates the application of concrete beams reinforced with pseudoelastic SMA longitudinal bars to evaluate the applicability of SMAs as alternative reinforcement,and to provide benchmark tests against the microstructure investigation to the performance of pseudoelasticNiTi used Malaysian ambient temperature for seismic mitigation design.The feasibility study of the superelasticNiTi SMA reinforcement bar for hybrid reinforcing of concrete beam also reviewed The factors influence the design and performance parameter of SMA in reinforced concrete beam,Comparison of NiTi,Steel and other Alloys,advantages and disadvantages,drawbacks and restraint of using pseudoelastic SMAs were also were studied.
