Strength of Grout‐Filled Damaged Tubular Members
Publication: Journal of Structural Engineering
Volume 113, Issue 3
Abstract
A simple explicit analytical expression, amenable to hand calculation, is developed for estimating the ultimate capacity of grout‐filled damaged tubular members. The analysis is based on the simplifying assumptions that: (1) Full interaction exists between grout and the damaged tube; and (2) grout provides sufficient support to the tube wall in the damaged region to prevent premature local buckling. The load‐carrying capacity is then obtained on the basis of the reduced section using beam‐column analysis similar in form to that adopted in current design codes. The first yield collapse criterion has been adopted. Experimental work was previously conducted on 10 small‐scale specimens. They were tested with different damage conditions. It is shown that the proposed expression provides close lower‐bound estimates of the experimental results. A parametric study is performed to establish the relationship between various parameters and their effects on the ultimate strength of grout‐filled damaged tubes.
