“…The crack strength and its relevant displacement was recorded when the first observable crack was obtained during the test. The yielding strength and the displacement were obtained according to the graphic method in post-calculation (Wu et al, 2019a(Wu et al, , 2019bYang et al, 2016). The load when the first observed crack happened will be recorded as the crack strength and its relevant specimen top displacement will be the crack displacement.…”

Concrete hollow blocks have the advantages of simplified construction, reduced construction time, and better thermal performance, and can thereby achieve energy conservation in building engineering and significantly improved thermal and mechanical performance. A new tenon composite block is presented to achieve better self-thermal insulation and mechanical performance by integrating thermal materials into blocks. The tenon composite block application requires satisfying mechanical and seismic performance. Therefore, to prove the mechanical and seismic performance of the tenon composite block, a low cyclic loading test was performed on two self-thermal insulation wall specimens: the tenon composite block and the “Martha” block (used as the comparison specimen). The crack distributions, failure modes, force–displacement data expressed using hysteresis and skeleton curves, mechanical parameters of strengths, displacements, ductility coefficients, stiffness degradations, and equivalent viscous damping coefficients of the two specimens were analyzed in the low cyclic loading test. By analyzing the specimen crack distributions and failure modes, the tenon composite block was proven capable of effectively connecting the heat insulation and loading bearing parts. The differences in the force–displacement data and the mechanical parameters between the tenon composite block and “Martha” block specimens, such as the higher strength and stiffness of the tenon composite block specimen and similar ductility performance with the widely applied “Martha” specimen, were mainly caused by the size differences between the tenon composite block and “Martha” specimens. Finally, suggestions for tenon composite block applications are proposed to overcome the limitations of the tenon composite block’s ability to consume seismic energy.

“…The shear wall structures are widely used to improve seismic performance of high-rise buildings, owing to their advantages such as lateral strength, stiffness, and ductility. Therefore, many studied focused on developing the precast concrete shear wall structure (Dong et al, 2018;Wu et al, 2019aWu et al, , 2019bZhu and Guo, 2019).…”

The seismic performance of the precast shear wall was improved by using a newly developed reinforced tenon to strengthen the precast joint, which is used to bear the shear force of the precast joint and reduce the effect of dowel action on the vertical connecting steel bars. The vertical connecting steel bars were only used to bear tensile and compressive stress and consume seismic energy. The seismic performance of reinforced tenon precast shear wall was investigated by quasi-static tests on one reinforced tenon precast shear wall specimen and one ordinary flat seam precast shear wall specimen. This study investigated the crack distribution and failure modes, precast joint slip of the two specimens, and the seismic performance parameters such as bearing capacity, stiffness degradation, ductility performance and energy dissipation capacity. The test results demonstrated that the reinforced tenon effectively reduced the slip of the joint surface and exhibited good ductility and energy dissipation capacity than that of the ordinary flat seam specimen, while the failure mode, bearing capacity, and stiffness were similar to that of the flat seam specimen.

To improve the thermal performance of external masonry walls, a new tenon composite block is proposed as the external maintenance component which contains the internal hollow concrete block part, the external block part, and the extruded polystyrene layer fixed by tenons. The production process and concrete material mixing ratio were optimized for the new tenon composite block to promote its application. The mechanical strength and thermal properties of the optimized tenon composite blocks were tested with experiments and numerical simulation in this study. The testing and simulation results indicated that after utilizing the two optimized concrete mixing ratios, the tenon composite block strength matched the strength requirements according to the related design code. The thermal performance of the tenon composite block wall was also good compared with that of a common block wall.
