ANALISIS PEMODELAN PLAT LANTAI DENGAN MESH DAN TANPA MESH TERHADAP BIAYA PROYEK KONTRUKSI

Abstract

tructural analysis is huge influence on the success of building construction. Structural analysis in SAP 2000 floor slabs are considered as structural elements like beams and columns, the load acting on slab is an uniform load. So that the even load will be directly distributed only to the edges of the slab element. Meshing of the slab is done so that the even load of the slab is also channeled to the beam.

This research aims to determine the difference in construction costs due to differences in slab modeling. In this study the researchers used an analytical descriptive approach. The analysis was carried out on the floor slab modeling without Mesh, Mesh 100cm, Mesh 50cm, Mesh 25cm and Mesh 10cm which had been loaded according to the rules, to find out the safe structural elements.

Based on the analysis, there is an increase in beam dimensions in modeling with Mesh, namely Beams B1 and B4 for Mesh 100cm and Beams B1, B3, and B4 for Mesh 50cm, 25cm and 10cm. The construction cost of slab modeling without Mesh is IDR2,940,502,000, slab modeling with Mesh 100cm is IDR3,102,855,000, slab modeling with Mesh 50cm is IDR3,205,698,000, slab modeling with Mesh 25cm is IDR3,205,329,000, slab modeling with Mesh 10cm is IDR3,275,332,000. The difference in construction cost of modeling without mesh against each modeling method with Mesh is IDR162,353,000 or 5.52% against Mesh 100cm, IDR262,196,000 or 8.92% against Mesh 50cm, IDR264,827,000 or 9.01% against Mesh 25 cm and IDR334,830,000 or 11.39% against Mesh 10cm.
