PERBANDINGAN SIMULASI GAYA AKSIAL DAN LATERAL PLAIN WALL BETON RINGAN ANTARA CAMPURAN STYROFOAM DENGAN LAPISAN COATING DAN ABU SEKAM PADI DENGAN FLY ASH

Abstract

A wall is a solid structure that limits and sometimes protects an area that is mounted vertically. The results of previous research by Enda et al., 2016 and Puro, 2014 stated that the use of materials from various limb materials has a sufficiently good bearing capacity to be used as various needs for lightweight concrete. The use of lightweight concrete as a wall is quite effective because the main function of the wall is not as the main structure in a construction. But in fact the wall also affects the forces acting on the surrounding structures. This makes the walls also affect axial and lateral forces. This study aims to study the behavior of lightweight concrete plain walls due to axial and lateral loads using the finite element method modeling. The scope of the lightweight concrete carrying capacity used is taken from a literature review of previousresearch results. Panel walls are modeled as 3D solid elements. The conclusion that can be drawn from this research is the stress information due to the work load and the deformation that occurs on the wall, which is to determine the location of the damage to the panel wall. The simulation results show that when the load is 1000 N, there will be a maximum deformation of 0.002 mm on the lightweight concrete walls of Enda et al and 0.16 mm on the light concrete walls of Sarjono puro, and experiencing stress of 0.084 Mpa on the two lightweight concrete walls. In simulations, Enda et al's lightweight concrete walls are stronger than Sarjono Puro lightweight concrete walls, meaning that concrete with Styrofoam material with a coating layer is better than lightweight concrete with rice husk ash material with fly ash. From this information, it can be seen that the recommended workload is able to withstand the panel wall
