KAJIAN EKSPERIMENTAL DINDING HOLCIM TERHADAP BEBAN LATERAL SIKLIK

Abstract

Recent earthquakes in various parts of Indonesia have caused many structural failures. The largest percentage of the damage is in clay brick and concrete brick simple masonry houses. Common Indonesia houses use either clay brick or concrete brick as the main material for walls. In the implementation, the use of such materials for structures shows inadequate performance in resisting earthquake load. This motivates PT Holcim Tbk to make innovation known as house solution product. The objective of this research is to identify the comparison between characteristics of various type of walls. To identify characteristics of Holcim wall damage models, such as crossloads, stiffness, cracking pattern and ductility, this research used walls in 3000x3000x140 mm dimension that consisted of Wall Without Opening (WTO) and Wall With Opening (WWO) made from Holcim concrete-brick material. Loading method used alternating load for modeling the earthquake and based on ACI 374.1-05 (American Concrete Institute) standards. Results of this research showed that Ppeak for WTO specimen was 71.08 kN or 34.93 % more Ppeak for WWO (46.25 kN). Displacement at Ppeak for WTO specimen was 3.93 mm or 30.69 % smaller than WWO specimen which had displacement of 5.67 mm. Holcim concrete-brick material showed better quality than clay brick and concrete block. Damages occurred were more of shear and sliding types
