Various methods of structural reinforcement and retrofitting have been developed with the aim of finding the most effective and efficient methods. In this research is used retrofitting method by adding profile steel structure in reinforced concrete beam. This method is done by adding the WF steel profile to the reinforced concrete beam which will increase the moment of inertia so that it will improve the ability of the structure to hold the working load. Used steel WF 250.125.6.9, as a reinforcement using shear connector. With the addition of this steel profile the beam strength is eligible to withstand the loads.

The fire was centered on the 1st and 2nd floor. Data retrieval include visual observation, carbonation test, concrete hammer test, concrete core test and tensile test of steel reinforcement that was held on January, 2011. All data that was taken will use to analyze the structure. Observations indicate that the temperature of the fire around 400 o C. Beams and columns on floors 1 and 2 had cracks and the quality of concrete fell 62% from 21.15 MPa to 14 MPa at the outer cross-section. While the floor plates 2 and 3 having a width of cracks and residual concrete quality is only 11.57 MPa. Pushover analysis (static lateral load) is a nonlinear static analysis that can provide detailed information about the collapse behavior of structures against earthquake loads, while the performance point is the magnitude of the maximum displacement of the structure during an earthquake plan. Results of 3D nonlinear static pushover analysis on the structure of Pasar Butung shows that performance point is achieved when the base reaction V reach 484.97 tons with displacement of 0.021 m (2.1 cm) at step 3. Results of analysis showed that the performance of the structure is still within the limits of Life Safety
