| Summary: | The yield-line method of analysis is a powerful tool that can be used to rapidly estimate the limit load sustainable by a reinforced concrete slab. In recent years, it has been limited in use due to its difficulties to computerise. Consequently, the Discontinuity Layout Optimization (DLO) procedure has been proposed to provide a systematic means of automating the method. In the DLO formulation, the size of the underlying optimization is highly affected by the number of the potential yield-lines generated. In this paper the concept of domain of influence in the framework of mesh-free methods will be introduced to the DLO method, resulting an efficient DLO method that can provide accurate solutions compared with the original DLO method while the problem size is very much smaller. |
