| Research Abstract |
In statically indeterminate reinforced structures, there are many cracks caused by longitudinal tensile stress such as shrinkage of concrete, temperature change and other severe conditions. This paper reports the results of the experimental and/or analytical study on the capability of pre-cracked reinforced concrete members.
The experimental results showed that many members increase the shear strength due to the initial crack. The above results were presented at CSSCE(2001) and CONSEC(2001).
In the numerical study, two kinds of finite element (the isoparametoric shell elements and three dimensional solid elements) was used for the response analysis of the pre-cracked reinforced concrete member. Also, the response analyzes for repair techniques of reinforced concrete pier were carried out using the FEM based on the three dimensional solid element.
These results were presented at DRRDAG(2000), APCSSS(2000), and CSSCE(2001).
