“…The first is the horizontal vibration along the depth direction, the second is the horizontal vibration along the width direction, and the third is the torsional vibration. The frequency of the depth-direction vibration is slightly smaller than that of the width-direction vibration, which (10) means that the depth-direction stiffness is smaller than the width-direction stiffness.…”

“…Zisis [9] studied the wind-induced vibration performance of residential timber buildings normally seen in North America with experimental and numerical methods. Malone et al [10] established an FEM of a local timber building with pinned connection joints with the software SAP2000 (Structural Analysis Program 2000) and achieved force-transferring paths under wind action. In the study presented by Morrison [11], particular attention was given to the failure modes of a low-rise building during a wind tunnel test.…”

Traditional Chinese timber buildings are lightweight, flexible, and quite vulnerable to wind. This paper aims to present a methodology for evaluating the wind-induced vibration performance of early Chinese hall-style timber buildings based on numerical simulations. First, the architectural and structural characteristics of early Chinese hall-style timber buildings were presented and analyzed. It is found that the main hall of the Tianning Temple can be considered a representative to carry out the research. Second, the wind pressure coefficients of the main hall were determined via computational fluid dynamics (CFD) simulation. Finally, the time-series wind pressures were generated, and the wind-induced vibration performance was analyzed by the finite-element method (FEM). The CFD simulation results show that the eave corners bear the maximum wind suction, and the windward pediment bears the maximum wind pressure. The FEM analysis has revealed that the lateral structural stiffness in the depth direction is smaller. Under the depth-direction wind load, most of the large displacement occurs intensively at the middle part of the windward frames. The structural response is dominated mainly by the top three vibration modes. The time-series wind vibration coefficients are larger than the code values by a factor of 1.39–1.82. This study can provide a reference for evaluating the wind-induced vibration performance of early Chinese hall-style timber buildings.

The Hani Rice Terraces are a famous World Heritage Site. The mushroom houses in the terraced fields have a unique architectural style and national cultural characteristics. This study focused on four traditional villages with the most obvious characteristics of mushroom houses: Azheke Village, Dayutang Village, Yakou Village, and Dayazi Village. A total of 34 mushroom houses were mapped. The forms of the mushroom houses were classified first, and then, the basic prototype of the building structure of the Hani mushroom houses was extracted for structural modeling. Finally, the structure of the prototype of the mushroom houses under different load conditions was analyzed. The results show that the Hani mushroom house design has a simple structure and good stability, can adapt to the local natural environment, and is the product of the Hani people’s adaptation to the local natural environment.

“…In both studies, the sheathing panels were considered as continuous in their models ignoring sheathing gap, and the effect of sheathing nails was incorporated into the wall and roof panels by adjusting the sheathing's shear modulus. Their modeling methods were later used by Malone et al [126] to compare the structural load path of a timber frame (TF) and a light-frame (LF) structure. It was found that TF outperformed the LF in both resisting uplift and story drift because continuous posts resisted out-of-plane wind loading more effectively than platform-framed exterior walls did, and the structural insulated panels used in the TF had greater stiffness compared with the LF shear walls.…”

The unsatisfying performance of light-frame low-rise buildings under hurricane winds is a long-standing issue. Most past research effort has been made in creating a wind pressure database using advanced testing facilities, studying "cutout" subassemblies (i.e., roof subassemblies/sheathed shear walls) without considering the imparted influences of the whole system, analyzing load transfer mechanisms within full building models in the linear range, and quantifying building performance for the purpose of estimating economic losses. What still remains unclear is the contribution of some key factors, such as the simplified spatial-temporal varying wind loads, the resolution of numerical models, and the building component capacities, with large uncertainties, to the ultimate building performance. This paper aims to review the state-of-the-art research of four related disciplines that may contribute to a rational building performance assessment from an engineering perspective. Hurricane hazards, public wind pressure databases, and design wind loads are reviewed to indicate the importance of parameters other than wind speed to the building performance. The evolution of the low-rise building FE modeling is summarized with an emphasis on the connection modeling as well as their comparisons with experimental measurements. The quantification of the building performance is discussed by using stochastic finite element modeling techniques. At last, areas requiring future studies are identified to fill knowledge gaps.
