Abstract

The purpose of this study is to compare two methods of seismic load analysis, namely the static equivalent method and the dynamic response spectrum method. The case study is the integrated service building of Tribhuwana Tunggadewi University, Malang City which has 5 levels and is located in the 4 (medium) earthquake zone with moderate soil conditions. The research method used is descriptive quantitative. Collecting data of project drawings, as well as observations and interviews. Analysis method Equivalent static and dynamic response spectrum using software Staad Pro. The results compared are the base shear force (V), the floor lateral force (F), and the displacement or displacement. The result in the form of maximum internal force is analyzed to determine the capacity or ability of the profile to withstand combined loads. The comparison of base shear and displacement does not differ much from the two seismic analysis methods used. This insignificant difference is in accordance with the SNI that for structures with a height below 40m can be analyzed using equivalent statics, while in the case study it only has a height of 30m. So that the equivalent static analysis becomes more accurate to use because the analysis process is simpler than dynamic analysis, but for structures with a height above 5 floors it is recommended to use dynamic analysis. The results of the analysis of the ability of the steel profile on the cross section of the column and beam indicate a safe condition in carrying combined loads.

Abstract

The demand for building quality in the construction of structures is a major requirement. One part of the structure is the floor slab work. The main obstacle is when the floor slab is loaded there will be deflection and bending moment. Meanwhile, there are demands for shorter work times at lower costs. This study aims to analyze the concrete slab against the flexural strength test, compressive strength test and tensile strength test of plate reinforcement. In this study, plate reinforcement used plain steel with a diameter of 6 mm and 8 mm. Then the plain iron reinforcement plate was compared with the M6 ​​and M8 wiremesh reinforcement plates. The results showed that the flexural strength test for plain iron reinforcing plates with a diameter of 6 mm was 45000 Kg.cm, while for a concrete slab with wiremesh M6 reinforcement it was 42500 Kg.cm then for reinforcement with a diameter of 8 mm it was 32500 Kg.cm while wiremesh M8 was 57500 Kg. .cm. This shows that the concrete slab with wiremesh reinforcement is better able to accept the load, as well as better moment capacity in bending, compressive and tensile tests compared to conventional slabs.
