| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 89 === This study investigated the behavior of the RC frames containing walls and the retrofitting effect by using the Carbon Fiber Reinforced Polymer (CFRP) on the wall. At first, the Softened Strut-and-Tie Model (SST) is used to design the shear strength of the walls, then the concept of the capacity design is applied to exclude the failure mechanisms other than the shear failure of walls. Finally, the measured shear strength was compared with the analytical estimations of the SST model and the currently ACI 318-95 code on the shear strength.
The experimental data shows that there are significant differences on the strength and stiffness on the frames with or without walls. The effect of the 12 cm RC partition wall cannot be ignored in the design of frames. According to the experimental observation, the major failure mode of the specimens is shear failure of walls, and the measured strength located between the estimations by the SST model and the ACI code approach.
Due to the absence of the end anchorage of CFRP, the wall specimens retrofitted with CFRP performed not wall. Therefore, it is recommended that the end anchorage of CFRP should be carefully designed.
