Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The current model of dam feasibility model is not suitable for government projects such as dam projects which purpose is to build more to meet the needs of the community. This is because the feasibility value is based solely on economic viability, while the socioeconomic and cultural benefits post-construction are not taken into account at all. This research aims to create a model of dam feasibility that takes into account the social, local economy and cultural aspects. The effect of dam construction on these aspects is analyzed based on survey data and then the impact value of each aspect is converted into the weight of aspects on the new dam assessment method with AHP method. The ideal dam feasibility model formula that takes into account the social, local economic, cultural, and profit aspects of dams with their respective weight values is the economics of the dam (1x), Social (0.25x), Local economy (0.24x), Culture (0.23x). The average dam feasibility value rose from 1.15 to 1.64 with the ideal feasibility model formula. The results of the cluster analysis show that in some locations the dam's social – cultural aspects are significant enough that it should be taken into account in the feasibility model. In addition, the construction of dams that prioritize people's income is an aspect that should be prioritized in analyzing the feasibility of dams.
This paper presents an experimental study on repairing damaged beam-column reinforced concrete joints using carbon fiber reinforced polymer (CFRP). Eight specimens of exterior reinforced concrete beam-column joints were tested to identify an effective method for improving the performance of the joint in terms of lateral strength. These eight specimens were designed with four specimens using a grout repair and injection scheme, while another scheme with externally bonded CFRP sheets (EB) and surface mounted CFRP strips (NSM) was explored as different reinforcement options (NSM + EB combined). The test results show that with the addition of CFRP reinforcement, the performance of beam joints in damaged conditions can be significantly improved. In particular, the use of CFRP NSM strip schemes and CFRP sheets bonded externally to beams and joints can effectively remove the plastic joints from the joint area, thereby causing a ductile failure mode (beam bending failure), which demonstrates the effectiveness of this retrofit method. Where the NSM + EB scheme can improve performance against loads of 9.43%, 20.46%, 28.98%, 16.64%, respectively, compared to using only grout and injection.
