Reliability-based optimization of laterally loaded piles

A general approach to the reliability-based analyses and the optimum design s of laterally loaded piles (LLOP) is presented. This approach takes into c onsideration all behavior and side constraints specified by standard specif ications for piles. Additionally, the casual effect of corrosion of piles w ith time is considered in formulation with limiting state functions. The so lution to reliability-based problems is obtained by a computer program (REL LOP). A general reliability based methodology is developed and implemented in the developed computer program (RELLOP) for both element and system limi t states. Numerical examples demonstrating the feasibility of considering m ultiple limit states and system reliability requirements in the design of l aterally loaded piles are presented. Effects on the reliability-based desig n solution of allowable reliability levels, and time of exposure to corrosi on are also illustrated, (C) 1999 Elsevier Science Ltd, All rights reserved .
