ABSTRACT
This chapter is devoted to the analysis of the first type of repair, considering full grouting along the entire length of the dented member. Because of the need to know a repaired member’s performance, the analysis of grout-repaired cylinders is of importance and of a practical nature to engineers. There are three basic levels of analysis for grout-filled cylinders: beam-column analysis; moment-thrust-curvature integration analysis, and finite element analysis. The moment-thrust-curvature (M-P-ϕ) relationship that is used in conjunction with the numerical integration must be established first in order to analyze the behavior of a grout-filled tubular. In the analysis of an internal grout-repaired member the numerically derived M-P-ϕ and axial strain–axial load-curvature relationships are utilized in conjunction with numerical integration. The computer program DGROUT was used to conduct analysis of several dent-damaged test specimens studied in the laboratory.
