Abstract [en]

Progressive collapses may occur when a bearing wall is eliminated for various reasons. It can be a gas explosion or collision accident of a train or a vehicle, but also during renovation of a building component. After the wall has been eliminated, the building should be undamaged and not suffer a progressive collapse. Such an event can be avoided through a vertical link. The purpose of this study is to examine how secure today's vertical strap’sare against progressive collapse, and to find a solution for reduced risk of collapse Method: This study includes a literature review and a case study. The literature review was performed by a deepening of the existing literature that investigated the progressive collapse and the vertical drag strip. The studies found through the database Google school and Discovery. The case study was conducted in Kadesjös which is an engineering office where drawings and calculations were performed. Result: The result indicates that the vertical strap used today cannot withstand the design load if the entire wall (including the screw attachment) is eliminated. The threaded rod will then be pulled out of the floor and a progressive collapse occurs. By mounting a 70x70mm plate in the floor this can be prevented. Without the plate it takes only 58 kN to pull out the threaded rod from the floor, but with the plate the connection’s capacity is increased to 100 kN and then the anchorage pipe limits the capacity. Conclusion: The conclusion of this thesis is that a plate that increases the vertical strap’s capacity and thereby increases the safety against progressive collapse should be used.
