“…Pan [7] and Ye [8] agreed that the failure of sheathing-to-frame connections was the main reason of degeneration of the in-plane behaviour of a CFSSW. Seim [9] concluded that other than mechanical properties of the sheathings, strength of sheathing-to-frame connections also determines the in-plane lateral performance of CFSSW.…”

A series of researches on the behaviour of a new structural system, composite timber wall panel with cold-formed steel frames, are investigated under monotonic and reversed cyclic loading. In order to improve the in-plane lateral performance of the composite timber panels, sixteen different optimized composite timber panels were proposed and tested, including increasing the thickness of the sheathings, improvement with steel X-bracings, filling with straw and advance of connection between sheathing and wood framing. The main objective of the investigation is to explore the pervasive mode of failure, determine the quantification of the improvement in lateral performance of these optimized composite timber wall panels and evaluate the benefits of each optimization during the process of failure.

“…Those experiments have been crucial for the development of different analytical and numerical models to represent the response of different timber-framed walls and buildings [17][18][19][20], making it possible to enlarge the value of the findings through different parametric studies [21,22]. In the particular case of light-frame shear walls, past research has shown that the sheathing material [23][24][25][26] and the type of fixation to the base used are important variables in the local and overall behavior of such systems under lateral in-plane loads. It is expected that with the presence of the sheathing material and its stiffness, the load-carrying capacity and the stiffness under in-plane horizontal loads will increase.…”

In general, the satisfactory seismic performance of timber buildings can be partially attributed to the material characteristics of the wood itself and to the lightness of its own structure. The aim of this paper is to analyze the in-plane behavior of light timber walls panels through a series of monotonic and cyclic tests, and to evaluate how the sheathing material and the fixation to the base influence the overall response of the wall. Five tests are presented and discussed while the reliability of an analytical method to predict the response of the walls is studied. The sheathing material revealed to be important in the overall response of the wall. Moreover, the type of fixation to the base also revealed to be important in the in-plane response of timber walls. In-plane stiffnesses, static ductility, energy dissipation and damping ratio have been quantified.

Background and Methods:This paper illustrates a research on the behavior of the composite timber panels used in a new-type cold-formed steel shear wall, when subjected to monotonic and reversed cyclic in-plane loading. The framing members of this new-type cold-formed steel shear wall are made of cold-formed steels. The inner timber frameworks, sheathed with veneer plywood, form the composite timber panels. Objective:In order to improve the lateral performance of the new-type cold-formed steel shear wall, two different optimized composite timber panels were proposed and tested, namely, increasing the thickness of the sheathings and the addition of steel X-bracings. The main objective of the study is to determine the quantification of the improvement in lateral performance of these two optimized composite timber panels. Results and Conclusion:Observed failure modes, structural performance parameters and the data of the strain gauges were given for each specimen, which indicates two optimized panels both have better lateral performance. But larger deformation and damage of the sheathings happened on the panels with steel X-bracings, so the panels with thick sheathings are more suitable and practical for normal use.
