“…The choice of pile foundation is based on the principle of equivalent area, which can be used to simulate the design of embedded model piles, all set as to the standard three-dimensional SOLIDE95 element unit before the process of simulation (λ = 0.15, ρ = 1,900 kg/m 3 , E = 1,076 MPa), so it is possible to adapt to the complex geometric mesh partitioning while maintaining high computational accuracy. [37] The SOLID95 element in the software is a higher-order element that can be used in irregular shapes, which has no effected on accuracy as well. SOLID95 unit is defined by 20 nodes; each node has three degrees of freedom, which means the coordinates of the node as the X, Y, and Z direction under the process of simulation.…”

Summary The tilting of buildings not only leads to inconvenience but also causes serious building collapses with heavy casualties and serious social impacts. However, rectification and reinforcement construction method started late in China. Now, this construction pattern mainly depends on sophisticated design techniques, without systematic techniques to reference. Based on the in‐depth analysis on tilt reason of a brick‐wooden building in Yunnan Province in China and combined with jacking rectification method, the impact pile project, artificial inserting shield engineering for steel box girder project, unbonded prestressed engineering project and concrete filled steel tube reinforcement example. Analyzing the multipoint synchronous lifting process by 3‐dimensional numerical simulation in ANSYS finite software. The actual monitoring results showed that the maximum inclination rate was reduced to less than 2.95‰ in the end, and the architectural distortion was stabilized in the process of rectification and reinforcement, which guarantees building safety and efficiency in the process of rectification.

“…Xie et al [18] derived a theoretical equation for the bending moment and rotation angle of a dovetail joint based on the force transfer mechanism of the joint and analyzed the factors affecting the bending moment in the joint. Seo et al [19] conducted a similar study of typical joints in the ancient Korean residential architecture. ey used static and cyclic loading tests on a prototype frame model and resulted in a trilinear model of the hysteresis curve of displacement and load.…”

The mortise and tenon joints are the main connection forms used in ancient timber buildings, and damaged joints have a critical effect on the safety of a timber structure. There are three main damaged cases of dovetail joints which are pulling, contraction, and mixing damages. In this study, using a theoretical analysis of the stress distribution in a mortise and tenon joint resulted from the pullout damage, a theoretical equation for the resisting moment of the joint was proposed. A finite element model was used to simulate the cyclic displacement loading of a frame with intact joints and with different levels of pulling and contraction damaged joints. The results show that the moment capacities both for the test and the simulation were in good agreement with each other. The simulation results also indicated that there are no changes in the capacity and energy dissipation of the pulling damaged joint compared to that of the intact joint, and good seismic performance still was provided when the pulling damage was less than 2/5 of the joint length. However, the capacity of the contraction damaged joint was significantly reduced, and its seismic performance was tolerably lost. The seismic performance of a mixing damaged tenon with the same degree of pulling damage was between that of the pulling damaged tenon and the contraction damaged tenon, and generally, it was controlled by the contraction damage. The friction between the tenon and the mortise is the main source of resisting moment and energy dissipation ability.

“…There are the limited research results on stiffness, especially for the heritage timber beam-column connections. It is noted that no accurate values can be adopted here to describe the stiffness of the joints (Maekawa et al 1998, Seo et al 1999, Uchida et al 1998. There is also growing recognition that the uncertainties associated with assumed boundary and continuity conditions, material properties, mass and mass distribution, dead load distribution, etc., drastically reduces the accuracy of finite element models for heritage buildings.…”

Due to the changing environments and aging, the structural resistance of the heritage buildings has been reduced significantly. It has become crucial to monitor and protect the architectural heritage buildings. The objective of this research is to monitor and assess the performance of the heritage Tibetan timber building in operational environments. A threestorey corridor part of the typical heritage building was chosen in the study. A long-term monitoring system was installed in the building to collect the structural response and the temperature. The detail finite element model was built based on the site investigation and existing documents, and updated based the temperature-based response sensitivity using the field monitoring data. The updated model was further evaluated using the static and dynamic analysis for condition assessment of the building in operational environments. The results show that the updated model is effective and accurate to predict the structural behaviour of the building in operational environments. Based on the temperature-based response sensitivity, it is capable of tracking structure performance throughout the life-cycle allowing for condition based maintenance and structural protection.
