“…For this reason, the verification of the structural performance of the SmartWall façade system in terms of seismic resistance is mandatory. So, the SmartWall that is planned to be installed in Greece is assessed using the Floor Response Spectrum (FRS) method by conducting seismic shaking table testing (Panoutsopoulou, Meimaroglou, & Mouzakis, 2023).…”

The residential sector is responsible for the largest share of global energy consumption, while the existing building stock in Europe is relatively old. This issue, in combination with the low rate of new constructions, highlights the necessity for deep renovation of existing buildings to reach NZEB standards. At the same time, in the last decades, off-site prefabricated solutions have gained popularity in the building market, allowing the reliable and effective integration of diverse components and reducing the total renovation cost and occupants’ disturbance. The current study describes three all-in-one “Plug & Play” prefab renovation solutions and their assessment in terms of thermal, static, acoustic, and fire performance. The assessing performance is selected depending on their incorporated element as well as the national regulations of the country where the renovation solution is going to be installed. The assessment aims to ensure their characteristics’ satisfaction with the European and national requirements. In parallel, the assessment identifies the accurate behaviour of prefab façade systems both in passive and active mode and improves/optimises any possible design drawbacks.

“…Lydia, Zhang, and others conducted damage treatments on wooden components by designing extreme climatic conditions and improving laboratory decay methods. This simulated the mechanical performance degradation of wooden components in real decay environments [26][27][28]. Ma and Chen et al conducted experimental research on the removal of damaged mortise and tenon joints from ancient wooden structures and found that as the degree of damage increased, the mechanical properties of the joints decreased significantly [29,30].…”

(1) The Hoop Head Tenon-mortise Joint (HHTMJ) in the Tusi Manor in Tibetan areas in Yunnan, China, has a serious decay phenomenon. To understand the effect of decay on the seismic performance of HHTMJ, (2) the five groups of HHTMJ and small-size Pinus kesiya var. langbianensis wood mechanical property testing specimens were placed in an artificially set decay environment and cultivated together with wood decay fungi for 0, 6, 12, 18, and 24 weeks, respectively. Low-cycle repeated loading tests were conducted to compare the failure mode, hysteresis curve, skeleton curve, and cumulative energy consumption of the HHTMJ under different decay cycles. (3) The results indicate that the failure mode of the HHTMJ is fractured at the tenon shoulder, and the deformation and failure of the tenon increase with the increase in decay. Compared with the non-decayed specimens, the ultimate bearing performance of the specimens after 6, 12, 18, and 24 weeks of decay decreased by 8.83%, 16.97%, 19.69%, and 30.22%, respectively. The cumulative energy consumption decreased by 21.6%, 27.4%, 33.2%, and 41.3%, respectively. (4) Decay primarily occurs on the exterior of the tenon, with minimal decay on the interior. The degradation of seismic performance in HHTMJ is relatively close to the degradation observed in small-size wood specimens during mechanical property testing.

This paper comprehensively investigates the moment-rotation relationship of straight mortise-tenon joints commonly used in Chinese antique timber buildings, focusing on analyzing the local compression mechanism at the tenon end-mortise and the tenon neck-mortise contact areas. Different compression tests were performed, and the experimental compressive stress-strain curves displayed a typical bi-linear response comprising an elastic increasing response followed by a plastic stage. The specimens subjected to middle local compression tests exhibited higher yield stress, elastic modulus, and plastic modulus than the others. Cyclic loading tests were conducted on twelve mortise-tenon joints with varying lengths, widths, and heights of the tenon to investigate the rotational behavior of the joints under alternating loading directions. The hysteresis curves of the tested specimens generally showed a “Z” shaped pinching effect, indicating limited energy dissipation of the joints during cyclic loading. The length and width of the tenon were observed to have a significant influence on the joint rotational behavior. Finally, a theoretical model was proposed to predict the moment-rotation relationship of the mortise-tenon joint, considering the proposed bilinear stress-strain relationship for wood under compression perpendicular to the grain. The predicted results obtained by the proposed theoretical model were generally validated by the experimental results.
