Shaketable testing ofelfcentering precast reinforced concrete frame with shear walls. the seismic performance ofelfcentering precast reinforced concrete rc frame with shear walls was investigated in this paper. the lateral force resistance was provided by selfcentering precast rc shear walls spcw, which utilizeombination of unbonded prestressed post.
The column parameters slenderness, material properties, reinforcement, mass at the top, etc. are equal for all tested structures. the foundation of the columns is placed onhake table in variantsver0 mm thick layer of limestone sand, ii over00 mm thick layer of limestone sand, iii foundations fixed to the shake table.
The work reported in this paper reviews modifications to existing codes to incorporate fibre reinforced polymer frp reinforcement in reinforced concrete rc structures focusing on shear resistance.
This study presents an overview of the impact resistance of frp strengthened structures including reinforced concrete rc beams, rc slabs, rc columns and masonry walls. although some issues still need to be investigated and clarified, it can be concluded that frp can be utilized to strengthen and protect structures against impact events.
