Model updating of seven-storey cross-laminated timber building designed on frequency-response-functions-based modal testing

“…In joints with small friction (such as those in CLT floors), sliding between the CLT panels might occur for service dynamic loadings. According to the laboratory tests presented by Brandner et al (2017), D'Arenzo, Casagrande, Reynolds, andFossetti (2019), Oh et al (2017) and Yasumura, Kobayashi, Okabe, Miyake, and Matsumoto (2016), the connections influence the in-plane stiffness of CLT floors and walls. Moreover, this stiffness is non-trivially dependent on several other factors, such as panel fabrication, boundary conditions affecting the development of shear mechanism, and the number and orientation of panels in a composition.…”

“…Moreover, this stiffness is non-trivially dependent on several other factors, such as panel fabrication, boundary conditions affecting the development of shear mechanism, and the number and orientation of panels in a composition. Studies by Ashtari, Haukaas, andLam (2014) andD'Arenzo et al (2019) concluded that the sliding between the panels is the main factor contributing to the in-plane flexibility of CLT floors.…”

In-Plane Deflection of Cross-Laminated Timber Diaphragms

“…A rigid diaphragm transmits loads to supports in proportion to the stiffness of the supports, whereas flexible diaphragms deformed in-plane through bending [2]. The lateral load distribution is influenced by the material properties and the load-slip behaviour of the connections between the adjacent panels (called panel-to-panel connections) and panel-to-beam connections [3]. Beairsto, in 2020 [4], evaluated the ductility of two large CLT diaphragms under monotonic and cyclic loads.…”

Experimental and numerical study on the in-plane behaviour of a new long-span assembly composite floor system under lateral load

“…For a modular steel-timber composite floor, Cristiano Loss [10][11][12] analyzed and studied the in-plane stiffness and bearing capacity of the floor system, and some relevant design suggestions are put forward. D' Arenzo G et al [13]proposed an equivalent frame model to model the in-plane deformation characteristics of prefabricated wooden floor, which can quickly obtain the in-plane stiffness of the floor. Ma Zhong et al [14]pointed out that the assembly direction has a great influence on the mechanical performance of floor,compared with loading parallel to joist, loading perpendicular to joist could greatly facilitate the floor system to achieve higher strength and in-plane rigidity , but all of the values of in-plane rigidity were lower than 10kN/mm under both loading modes.…”
