Re-planning of Concrete Structures in the Ngoro Dormitory Project in Surabaya

The current trend of building construction is using steel frames and reinforced concrete frames. design concept based on strength limit analysis (ultimate strength) which has sufficient ductility to absorb earthquake energy according applicable regulations. In addition this, it also necessary consider the economic aspect. All these structural considerations will influence planning alternatives, such as column layout, beam length, span. Dormitori Ngoro Surabaya one low-rise buildings that be redesigned comply with SNI 2847:2013. This research expected answer need for earthquake-resistant ETABS program 2847:2013 standards. this study method used Flowcharts in order facilitate stage. As study, produced a maximum moment 137.58 KNm use dimensions 40 x 75 cm, 8D16 top main reinforcement 3D16 bottom stirrups D10-200 support area D10-100 field area. Whereas ratio manual calculations 0.24% results are 0.22%.
