Seriously damaged structures need to be dismantled, but strengthening methods can strengthen the lightly damaged structures. This study uses the most popular strengthening method- the steel plate reinforced concrete, but it can’t endure high temperature. So the fireproof coating material needs to be adhered to the steel plate in order to protect the integrity and durability of the structures. The objective of the study is to understand the relationship between the thermal energy absorbed by adhesive interface and the remained shear strength of the specimens after heating in order know the effects of fireproof coating materials and if the steel plates combine closely with concrete. The main testing variables of the study are the variations of temperature, rising temperature curves and fireproof coating materials. Thermal conductivity, DTA, GTA and temperature of the specimens are measured so as to realize the relationships of thermal energies. Study results show that the adhesive interface between 150℃~170℃ will suffer a loss of weight through the testing of TGA. No matter what kinds of rising temperature curves and whether fireproof coating materials are used, the relationships between the absorbed thermal energy and the remained shear stress in adhesive interface form two certain tendencies. The study also shows that when the temperature of the steel plate reinforced concrete is measured, the thermal energy can then be gotten through calculation; the remained shear stress and fracture modes can also be obtained by the equations from the tests.
