Perbandingan Kuat Geser dan Daktilitas Dinding Bata Merah, Batako, dan Bata Ringan

Abstract

In recent decades, a number of earthquakes have hit various parts of Indonesia, causing damage and loss of lives. Basically, earthquakes do not cause direct casualties. The collapsed or damaged buildings do. Masonry wall houses are a class of non-engineered structures. These structures were suffered the most damage subjected to earthquakes in Indonesia, for example during the 2006 Yogyakarta Earthquake and the 2018 Lombok Earthquake. The reason was these structures did not meet the earthquake-resistant building provision and the structures were mostly built by grassroots construction workers. As an effort to reduce the risk of earthquakes disaster, innovations in earthquake-resistant houses need to be encouraged, including innovations of masonry walls. This study aims to compare the shear strength and ductility of standard brick, concrete block, and lightweight brick walls that have become more popular to the people with a thickness of 6 cm, 8 cm, 10 cm, and 12 cm through laboratory testing. The diagonal tension (shear) test was carried out following the regulations of SNI 4166-1996 and ASTM E519. As a result, in terms of earthquake-resistant building criteria, lightweight brick walls have several advantages, namely lighter weight and greater shear strength compared to standard brick and concrete block walls.
