Pushover Experiment of Portal Structure with Brick Wall without and with Anchor for Non-Engineered Building

Abstract

Based on the findings in almost all earthquakes that hit Indonesia, the damaged and collapsed buildings were simple houses built spontaneously (non engineered building), where buildings are built based on practical experience without structural calculations. One form of damage to non-structural components and structures is the relationship between columns and brick walls, where cracks and separation between columns and walls occur due to no anchor. So the design of buildings in the future is safe from the dangers of earthquakes. For earthquakes that are not too large, the building is likely to remain standing with little damage. However, to anticipate a strong earthquake and reduce the adverse effects, the building of a walled wall must be built according to the provisions of earthquake-resistant building construction by providing reinforcement in certain parts such as mounting anchors from column to wall. To find out how much influence from the installation of the anchor from the column to the brick wall, an experimental study was carried out on the walls completed with a foundation, sloof, column and beam. There were 2 specimens, namely specimen that uses the anchor and do not use anchor, so it is expected to know the behavior of mounting anchors. From the test results obtained that a pushover load of 7540 kg and a displacement of 56.5 mm for specimens using anchor while for specimens that did not use anchor had pushover 5666 kg and a displacement of 48 mm. The conclusion is the installation of anchors between column and brick wall can increase
