Perencanaan Struktur Parkiran Bertingkat (Building Park) Obyek Wisata Telaga Sarangan Bermetode Sistem Rangka Pemikul Momen Menengah

Abstract

The vehicle parking building at the Sarangan Lake tourism object used in the planning and preparation of the thesis is located to the east of the lake. The building area is ±512 m2 and has 2 floors. Based on the results of the Standard Penetration Test (SPT), it is known that the building was built on land with moderate soil conditions (SD site class) and based on its function is included in risk category IV, so this lecture building is included in seismic design category C. In this final project, building modifications were made which is located on the roof, originally using a steel frame modified into a concrete plate. Structural calculations in this building will be planned using the Intermediate Moment Resisting Frame System (SRPMM) method.

Building planning refers to building construction regulations in Indonesia. Earthquake analysis in this planning uses the equivalent static analysis method based on SNI 1726:2012 concerning Procedures for Planning Earthquake Resistance for Building and Non-Building Structures and Indonesia's Hazard Map 2010 with a probability of exceeding 10% in 50 years, the entire structure is reinforced concrete referring to SNI 2847:2013 concerning Structural Concrete Requirements for Buildings, SNI 1727:2013 concerning Minimum Loads for the Design of Buildings and Structures, while structural analysis used the SAP2000 program. Control the need for reinforcement in the column using the PCAColumn program. The structural calculation process includes determining the structural system, loading analysis, structural modeling, internal force analysis, reinforcement calculation, and checking structural element requirements. The secondary structure is in the form of plates and stairs which are carried by the primary structure, namely beams and columns. The bottom structure consists of sloof. From the results of structural analysis using the Intermediate Moment Resisting Frame System method, the main beam dimensions are 50 x 75 cm and columns 70 x 70 cm with 12D25 reinforcement configuration. The results of the calculation of the reinforcement volume and the volume of the main structure concrete obtained a ratio of 181.397 Kg/m3 for the longitudinal frame and 162.488 Kg/m3 for the transverse frame. One of the economic levels of the planned structure can be seen from the ratio of reinforcement volume to concrete volume. At the end, the method of carrying out the column structure work is also included in the form of the stages of carrying out the column work.
