INTRODUCTION
Analysis and design of the structure experienced significant development with the development of structural analysis and design software. An increase which is very influential with the existence of structural analysis software is a matter of productivity in structural analysis and design. Before the existence of structural analysis software to do the analysis and design of multi-storey building structures will require a long time and result in the project planning process being delayed, with the software the analysis and design can be done quickly, so that it can streamline the planning time of a project. In planning the construction of buildings in Indonesia use the SNI 2847: 2013 regulatory guidelines, especially those involving concrete work. This procedure includes general requirements as well as technical provisions for planning and implementing concrete structures for buildings or other structures that have similar characteristics to building structures.
Computer programs are made to simplify and speed up calculations when compared to conventional methods, namely with a manual calculation calculator. Analysis of reinforced concrete structures will be easier with the application of programming languages with SAP2000 software. The output of this software is in the form of adequate dimensions, number and diameter of the longitudinal reinforcement and shear reinforcement, and the output forces. This application also provides benefits for planners because it is easier and more efficient. The results of this SAP2000 software output are the number and diameter of the longitudinal reinforcement and the shear reinforcement only in the beam and column structure, therefore this study only reviews the beam and column structure. This study aims to determine the comparison of building structure planning results using SNI 2847-2013 guidelines using SAP2000 V.19 software, especially in portal structures (beams and columns). Based on the background description above, the research problem formulation is as follows: 1) How is the modeling of building structure planning using SAP2000 V.19 software?, 2) How do the comparison of building structure planning results using SNI 2847-2013 guidelines using SAP2000 V.19 software especially in beam structures ?, 3) How do the comparison of building structure planning results using the SNI 2847-2013 guidelines using SAP2000 V.19 software especially in column structures The beam is one of the building structural elements whose main function is to accept bending and sliding loads, but not for axial forces. How to determine a structural element as a block we can do by clicking: "Define -> Frame Section -> Add New Property -> Concrete -> Rectangular.

Column Planning Concept Using SNI 2847-2013
The columns in a building function as supporting loads from beams and plates, to be transmitted to the subgrade through the foundation. The load from the beam and plate is compressive axial load and bending moment. According to SNI 03-2847-2013, columns must be designed to withstand the axial force from the factor load on all floors or roofs and maximum moments. Loading conditions that provide the maximum moment ratio to axial load must also be reviewed. The stages in analyzing columns: 1) Reinforcement for columns is made symmetrical reinforcement based on a combination of Pu and Mu, 2) Maximum column design load, 3) maximum column design moment for upper and lower end, 4) Value of fixed contribution to deformation, 5 ) Modulus of Elasticity, 6) The value of column and beam sensitivity, 7) Eccentricity Value, 8) Determine Ψa and Ψb, 9) The value of column slenderness, 10) Magnification of moments, 11) Reinforcement design, 12) Determine the reinforcement used, 13) Check Pu against balanced load, 14) Checking cross-sectional strength, 15) Shear Reinforcement.

Preliminary design is the initial step used to plan the dimensions of the structure of the building, the structure and structural components are planned so that all cross sections have a minimum plan strength equal to the strength needed to be calculated based on a combination of load and factored force in accordance with the arrangement. The combination of loading selected is the one which gives the greatest effect on the structure. The planned load combinations are shown in Table 2 below: 1,2 D + 1 L + 1 RSPX 1,2 D + 1 L -1 RSP X 1,2 D + 1 L + 1 RSPY A combination of temporary loading (due to dead, live, and dynamic earthquake response spectrum) Combination 10 1,2 D + 1 L -1 RSPY Combination 11 Combination 12 0,9 D + 1 EQX 0,9 D -1 EQX A combination of temporary loading (due to dead, live, and static earthquake) Combination 13 0,9 D + 1 EQY Combination 14 0,9 D -1 EQY Combination 15 Combination 16 0,9 D + 1 RSPX 0,9 D-1 RSP X A combination of temporary loading (due to dead load, and dynamic earthquake response spectrum) Combination 17 0,9 D + 1 RSPY Combination 18 0,9 D -1 RSPY
