Abstract:
The earthquake caused damage to buildings, especially simple houses that were not designed according to engineering rules. Damage caused by earthquakes is often found in the form of cracks to the collapse of masonry walls. Damage due to earthquake forces can be anticipated by increasing the strength of columns, beams, and brick walls. Especially for brick walls, this can be done by increasing the strength of the brick unit, mortar, and brick design that optimizes the function of the mortar. The regular brick stacking pattern produces a square bed joint and head joint area, while the hook-hole purus brick stacking pattern produces a square bed joint and an upright cylindrical head joint that connects from top to bottom. This study aims to determine the effectiveness of the use of PLB masonry in increasing the shear strength of the wall through laboratory tests using two groups of test objects. Laboratory test results were analysed to determine the shear strength of masonry walls based
on the SNI formula. Based on the results of laboratory tests, it can be concluded that PLB bricks have a strength of 13.64% greater than ordinary bricks.
