Yield Line Analysis: Predicting Slab Collapse Loads
Yield Border Analysis provides a robust approach for determining the ultimate, collapse weight of reinforced concrete slabs. Previously, these elements were assessed using elastic theory, which often underestimated their real strength, especially under extreme loading conditions. This analysis accounts for the formation of plastic joints and subsequent yielding zones within the slab, allowing engineers to more accurately determine the maximum force a slab can withstand before failure . The method involves identifying potential yield line patterns – essentially crack paths – that develop as the slab reaches its ultimate state; these patterns are then used to compute the decisive moments and shears.
