This paper presents the results of investigation on structural behavior of the load bearing walls of interlocking bricks system called Brickcool. The model of Brickcool load bearing walls with and without reinforcement were tested in the laboratory until they failed. Both models were prepared with the same dimension of 1.3 m height, 1.0 m wide and 125 mm width. The influence of reinforcement on the deflection and strain of the load bearing walls were examined. Physical and mechanical tests of the individual brick were also been carried out. Results of this study proved that the model of load bearing wall with reinforcement have higher failure load with lower displacement at the top of the wall. The presence of reinforcement in strengthening the wall panel also increase the compression and tension strain compared to the wall panel without reinforcement. The physical and mechanical test results also found that the bricks have satisfied the minimum requirement values set by the British and American Standards.

Lubrication Conditions

Bolted joints are among the most widespread and most important detachable connections used in mechanical engineering and construction. The common use of this connection group is reflected in the variety of types of screw connections. There are several geometric and material factors, and consequently tribological ones, that determine the load capacity and, which is often of key importance, the repeatability of the bolted joint. The paper presents a description of the test stand and the test results of preloaded bolted joints for different lubrication conditions. The measured parameters were the breaking force value of a double lap bolted joint and its repeatability and the axial force repeatability of the bolts tightened by an electronic torque wrench.

The Impact

Fiber waviness defects are found in the inner surface of the hat-shaped stringers manufactured by a process system. In order to establish the acceptance criterion for the stringers with the fiber waviness defects, experimental testing and numerical simulation were carried out in this study. Specially induced fiber waviness defects of four pre-defined severity levels were manufactured and tested. A maximum of a 58.1% drop in compressive failure load is observed for the most severe level in the experimental results. A finite element model with progressive damage method and cohesive zone technique was developed to simulate the failure process and the impact of fiber waviness defects. The numerical simulation results of compressive failure load have a good agreement with experimental results qualitatively and quantitatively. In addition, two simple parameters, i.e., aspect ratio A/H and the number of plies with fiber waviness, are proposed to characterize the influence of the fiber waviness on the compressive failure load for the purpose of fast engineering quality checks.
