Abstract
During the life cycles, reinforced concrete buildings frequently suffer
various degrees of damage due to natural or human causes, especially
after several catastrophic earthquake strikes in the recent years in Taiwan.
Considering safety and economic reasons, the method of repairing and
reinforcing was broadly introduced to those buildings in order to prolong
the service lives.
The behavior of structure suffering fire damage is so complex and it is
impossible to analysis this behavior by analytical method. Full scale
beam-column joint testing is very costly and time consuming. The use of
empirical equation from testing and numerical technique is feasible way
to investigate the behavior of structure suffering fire damage. 10
Beam-column joint specimens have been studied in this research.
According to Chapter 21 in ACI 318-05 ,and the heating curve in CNS
12514,the influences of high temperature on the normal concrete and
self-compacting concrete are discussed.
