Abstract: This study was conducted to develop finite element computer programs to calculate stresses and deflections in rigid pavements with cracks and joints subjected to loads and temperature warping, as well as in the supporting subgrade soil. This report is presented as a user's manual for the WESLIQID program, which deals with pavements on a liquid foundation. The program allows for analysis of pavements with full or partial loss of subgrade support over designated regions of the pavements. Variable slab thickness and modulus of subgrade reaction k are incorporated and any number of slabs arranged in an arbitrary pattern can be handled. Also, multiple-wheel loads can be used, and the number of wheels is not limited. The nature of the computer program and its programming logic are first delineated, followed by a general discussion on the efficient and correct usage of the program, e .g ., the efficient way of arranging nodal numbers to minimize the bandwidth. The input guide to the computer program is presented with a detailed explanation for each input variable. Five example problems with input data are presented and the computer print outs of three problems are included with detailed explanations.
