Adhesive bonding has established a remarkable interest in civil construction industry because of its proven success and wide application in aerospace and automotive industry. In fact, the application of adhesive has existed in construction of civil engineering facilities since 1960s in which the major application dominated by the segmental construction, externally-bonded reinforcement, structural repairs to concrete and also non-structural application. However, lack of design code and comprehensive research related to the use of adhesive bonding in load-bearing connections made this method of joining less attractive. Therefore, this experimental research was conducted to study the pull-out tension and flexural capacity of adhesively jointed steel plates. The effects of some of the critical variables on the performance of adhesive joint were investigated namely the overlapping length, curing temperature and joint configuration particularly single-lap joint. single-strap joint and double-strap joint. Only one type of commercially available structural adhesive namely Sikadur -30 was used to join the 100mm wide steel strips. It was observed from the test results that the stiffness and load carrying capacity of adhesive joints subjected to pull-out tension increases with decrease in overlapping length. Investigation the effects of the curing temperature; it was noted that at 45°C the adhesive was fully cured. On the other hand, the double-strap joint has shown much higher loading capacity under all loading conditions such as pull-out tension and bending. It has performed best amongst the three other types of joint designs investigated. The available results of this research study is a primary effort in order to establish the future research studies for adoption of adhesive joints as structural connection in the global construction industry.
