Methods for Investigate and Resolving Shear-Induced Wall Cracks

Over time, buildings undergo damage influenced by various factors. This vulnerability spans the entire lifespan of buildings, starting from the initial planning and implementation stages. A common consequence is damage to architectural components, particularly the formation of cracked walls. PU Ministerial Decree number 16/PRT/M/2010 identifies multiple factors contributing to wall cracks, including plaster layer expansion and shrinkage, vibrations from traffic, seismic events, and structural deformation. This research was carried out by making a wall construction prototype. The prototype will be given pressure as a lateral load so that the wall construction cracks. Test results indicate a deflection of 75 mm at a 498 kg load for a steel structure frame without brick masonry. Conversely, a frame structure with brick masonry showed a deflection of 27 mm. This comparison reveals the potential of brick wall pairs as stiffeners in steel structure frame construction. However, a cautionary note emphasizes that stronger brick walls may expedite the collapse of the structure by exerting pressure on steel columns, originally designed for tensile forces but experiencing bending forces when pressed against the bricks. Analyzing the test results and repairing techniques' efficiency underscores the reinforcement of walls as the most effective approach to addressing structural cracks due to shear collapse. This method withstands a lateral load of 581 kg, with an associated implementation cost of Rp. 293,125.00.
