<![CDATA[The addition of a floor is an alternative to a building and a development due to an increase in the function of the shophouse or an additional infrastructure but the available land is limited. In this study, an analysis of the structure of the existing building was carried out to determine the influence and capability of the structure when adding floors to the building. If the building structure is not able to withstand the loads that work due to the addition of floors, then elements that are not strong in the existing structure are required to strengthen the structure, strengthening with the concrete jacketing method. Analysis of the structure of the planned addition of floors by adding 1 floor so that it becomes 3 floors and then 3D modeling using the SAP2000 program. Building plan with a size of 16 mx 28 m, height 4 m on each floor, concrete quality (f'c) 30 MPa, yield stress (fy) 240 MPa for reinforcement diameter ≤ 10 mm, yield stress (fy) 400 MPa for reinforcement diameter > 10mm. The addition of the building floor to the structural elements and the loading is the same as the existing structure, the analysis of the earthquake with equivalent static and earthquake load analysis based on SNI. The result of structural analysis is the ability of the initial structure due to the addition of the floor. Reinforcement of structural elements with concrete jacketing, enlargement of dimensions and addition of reinforcement for beams and columns. Enlargement of beam dimensions 30/40 to beam 50/60, column 30/40 to 50/60. The addition of reinforcement was carried out because the calculation did not meet the requirements, 10 Ø 16 was added to the beam bearing area, 8 Ø 16 of the reinforcement field was added to the beam, while 14 Ø 16 was added to the column.]]>
