Extending the Collapse Time of Non-Engineered Masonry Buildings under Seismic Loading

Abstract eng:
THE COLLAPSE OF NON-ENGINEERED MASONRY IS ONE OF THE GREATEST CAUSES OF DEATH IN MAJOR EARTHQUAKE EVENTS AROUND THE WORLD. THIS PAPER INVESTIGATES A RECENTLY DEVELOPED RETROFITTING TECHNOLOGY SPECIFICALLY AIMED AT PREVENTING OR PROLONGING THE COLLAPSE OF ADOBE (MUD BRICK) BUILDINGS UNDER STRONG EARTHQUAKES. THIS TECHNOLOGY USES COMMON POLYPROPYLENE PACKAGING STRAPS TO FORM A MESH, WHICH IS THEN USED TO PREVENT BRITTLE MASONRY COLLAPSE. THE RETROFITTING TECHNIQUE IS TESTED USING STATIC, DIAGONAL LOADING OF MODEL WALL PANELS. IT IS SHOWN THAT THE PROPOSED TECHNIQUE EFFECTIVELY PREVENTS BRITTLE COLLAPSE OF THE PANEL AND THE LOSS OF DEBRIS. PARTIAL MESHES OF VARIOUS ORIENTATIONS ARE ALSO INVESTIGATED IN ORDER TO BETTER IDENTIFY THE ACTION OF THE MESH. FINALLY, A CASE STUDY IS PRESENTED FOR THE IMPLEMENTATION OF THIS TECHNOLOGY IN RURAL COMMUNITIES THROUGHOUT NEPAL.
