KAJIAN EKSPERIMENTAL STRUKTUR PORTAL BETON BERTULANG DENGAN DINDING PENGISI BATU BATA TERHADAP BEBAN AKSIAL LATERAL

Abstract

Masonry infill is usually used to separate one room with another room or element which functions as exterior partition of building. In low or medium building, masonry infill is installed after main structures have already finished, so installing the masonry infill and finishing the building done at the same time. Although the masonry infill considered as non structural element but it has inclination to connect to portal, by giving stiff and strength to structure when it is given strong horizontal load or earth quake. The purpose of the research is to find out characteristic of portal with masonry infill structure using steel and without using steel when it is given axial lateral load. The research show that portal with masonry infill structure using steel with dimension 0,75 m in height and 0,45 m in width is the strongest it can withstand to maximal load of 12,4 ton and has 16,3 mm deflection, even though portal with masonry infill structure without using steel with dimension 0,75 m in height and 0,45 m in width can withstand to maximal load of 9,3 ton and has 12,55 mm deflection, portal with masonry infill structure using steel has dimension 1,25 m in height and 0,5 m in width can withstand to maximal load of 10,4 ton and has 10,91 mm deflection and , portal with masonry infill structure without using steel has dimension 1,25 m in height and 0,5 m in width can withstand to maximal load of 11,2 ton and has 14,23 mm deflection.
