“…The timber structures of ancient buildings have existed for a long time [1], so they will inevitably be subjected to various loading effects such as seismic actions and wind actions. The safety of ancient timber structures is often compromised by the long-term effects of these loads [2]. As an important load-bearing component of wood structure of ancient buildings [3], the mechanical performance of wooden column is inevitably affected.…”

“…In recent years, there are many studies on wooden column. The effect of different sizes of column foot tenons on the hystereti behavior of wooden columns was studied via the quasi-static test [2]. The initial mode criteria of the rigid free-standing column to the plane motion of the traditional Chinese timber frame was studied via a combination of theoretical derivation and finite element simulation [4].…”

In order to provide some scientific references for the restoration of ancient timber buildings, the wooden column was subjected to a secondary load through the quasi-static test. The seismic performance parameters of wooden column such as the damage of the wooden column, P-Δ hysteretic curve, P-Δ skeleton curve and stiffness degradation were analyzed. The test results showed that the wooden column could still maintain the lateral resistance capacity after the secondary load under the action of low reversed cyclic load. The hysteretic curve of the wooden column had a certain degree of a pinch effect, which indicated that the semi-rigid characteristic of the wooden column was reserved after the secondary loading. The lateral stiffness of the wooden column after the secondary load decreases with the increased of the lateral displacement. The lateral stiffness decreases with the increase of displacement. It showed that the wooden column still had good seismic behavior after secondary load.

“…Wood is widely used in ancient buildings and modern buildings due to its convenient processing and unique mechanical effects. In ancient Chinese buildings, the structures are primarily built with wood (Li et al 2015;Han et al 2020). The timber structures of ancient Chinese buildings are worth studying because of their values, i.e., their artistic value, historical value, scientific value, social value, and cultural value (ICOMOS China 2015).…”

In order to provide more accurate suggestions for the restoration of ancient timber buildings, five types of specimens were designed for static loading tests. The tree species used for the specimens was larch. The wooden composite beams were composed of purlins, tie plates, and fangs. The study analyzed the effects of the number and position of dowels on the mechanical behaviors of wooden composite beams in ancient timber buildings. The bending moment, slippage, strain of the wooden composite beams under the deflection of the beam allowed according to code, and the ultimate bearing capacity of the wooden column composite beams under failure conditions were examined. The test results showed that the dowels could improve the bending capacity of the wooden composite beams. The even distribution of the dowels was beneficial in reducing the sliding effect of the wooden composite beams. Under the amount of deflection allowed by the code, the mid-span section strain along the height of the wooden composite beam approximately conformed to the plane section assumption. The wooden composite beam still had bending capacity after each member failed. The results of this study illustrated that dowels improved the overall mechanical properties of the wooden composite beams.

“…They found that the column and tie wooden construction has good deformation capacity and energy dissipation capacity, but poor ultimate bearing capacity and stiffness. Han et al (2020) researched the bending moment-rotational angle hysteretic curves, momentrotational angle skeleton curves, ductility, stiffness degradation, energy dissipation capacity, slippages between the wooden column and the plinth, and the damage of the column foot tenons. The test results showed that the rotation of the column foot tenon improves the energy dissipation capacity of the wooden column.…”

A restoring force model of through-tenon and half-tenon joints was studied with a certain level of universality. To address the differences among data collected under different test conditions, test data collected via through-tenon and half-tenon joints were counted and fitted, and their similarities were then generalized. To better simulate the gap and stiffness degradation between the through-tenon and half-tenon joints, the skeleton curves frameworks were simplified into four phases, namely sliding, elastic, yielding, and failure. The normalized control parameters collected through the characteristics of the framework of through-tenon and half-tenon joints, as well as the different coefficients of strength degradation and stiffness degradation were calculated. The hysteretic rules of the restoring force model of through-tenon and half-tenon joints were developed. Through case study, the results show that the MAPE (mean absolute percentage error) and R2 (coefficient of determination) of experimental data in the references and simulated data of through-tenon are respectively 12.570% and 0.735, while those of half-tenon are respectively 11.763% and 0.772; and the restoring force model of through-tenon and half-tenon joints being constructed had a certain level of universality. The results demonstrated that the construction of refined finite element analysis model of Chinese ancient timber architectures can be simplified to a certain extent to meet the pressing time for seismic performance analysis of many ancient timber architectures. It provides researchers with an innovative pathway to enhance the efficiency of seismic performance analysis of ancient timber architectures.
