Reliability and Stability Assessment of Concrete Gravity Structures (RCSLlDE): Theoretical Manual.
Abstract
The reliability analysis of retaining walls and concrete gravity structures can be based on existing U.S. Army Corps of Engineers Computer-Aided Structural Engineering (CASE) performance assessment computer programs and algorithms for walls and structures that were validated over many years of use. The programs can be used to define the performance functions for reliability assessment. The objective of this study is to develop a reliability assessment methodology of the stability of concrete retaining walls and gravity structures based on an existing CASE computer program for evaluating their performance. The performance function for reliability assessment was defined in accordance with the CASE computer program. The reliability assessment methods used in this study include the advanced second moment method (ASM) and Monte Carlo Simulation (MCS) using importance sampling (IS). Correlated and noncorrelated random variables can be handled by the program. The computational procedure was developed around the CASE program for Sliding Stability of Concrete Structures (CSLIDE). Also, a user interface for CSLIDE and the reliability program based on CSLIDE (called RCSLIDE) was developed using Microsoft Visual BASIC. The software development procedure in this study is significant because it establishes a prototype reliability software that is modular and based on an existing CASE program.
