Abstract
This research was conducted to analyse the alternative which might be done to give solution for column structure reinforcement and bar in case of building room layout change. There were 4 methods which were presented for analysing column structure reinforcement and bar in this research. The dimensions of the removed column were 25x40 cm with a length of 350 cm and the reinforced beams were 25x40 cm with span length of 800 cm. This research also showed the price which was gotten from various methods did as consideration of solution chosen. The analysis was conducted by using SAP2000 application. This analysis was done by 2 column removal without reinforcement which in the fact the structure is not powerful if there is not any reinforcement by the result of 2 column removal so that for safety anticipation, it is better if reinforcement is implemented. The first method is the method with the elimination of 2 columns but without the reinforced structure, after SAP2000 analysis on the portal, obtained the maximum moment that happened was 76,1 KN exceeding the permitted moments of 62 KN so that this will be dangerous to the strength of the structure, therefore for security anticipation should be done reinforcement. The second method which is the first solution is the method of Jacketing Column & Beam obtained the result that the building was considered safe by enlarging the original beam dimensions 25x40 cm to 35x65 cm and the original columns 25x30 cm to 40x40 cm. It is also supported by the value of the moments shown not exceeding the maximum allowed moments. The third method is an alternative to the second retrofit solution by providing additional structural elements instead of the existing missing columns, but with this method it will interfere with the aesthetic value of the building, since the new element beams are very visible. The last method is the use of CFRP (Carbon Fiber Reinforced Polymer), this method proved to be the most efficient way to overcome the structural reinforcement problems at As-Shohabat mosque in terms of processing time, labor cost, and sufficient strength to replace the reinforcement that occurs due to the reduction of the column that supports the block.
