What is Prowd?
Prowd provides an innovative method for rapidly calculating the bending moments and deflections of propped and cantilever retaining walls in clay soils. Soil strains are calculated using analytically and experimentally derived mechanisms and are linked to earth pressures utilising mobilisable strength design through the constitutive law proposed by Vardanega and Bolton (2011). The performance of this software in calculating equilibrium wall loadings during sequential excavation of propped excavations has been demonstrated by Deng et al. (2021).
This software is a work in progress and we would be grateful for any feedback on improvements that would make it more powerful or usable in Engineering Practice.
