“…Once the wall was analyzed, comparative graphs were made, in order to evaluate the differences between the different wooden structures' configuration in contrast with the FPSW test. For example, compare walls that had the LFTB system (Guíñez et al 2019) with nails (ϕ3x70mm) every 100mm versus the CLT wall (Popovski et al 2011) with 10d annular ring nails per angle bracket. in contrast FPSW configuration, (see hysteretic envelope from Fig.…”

Seismic Behavior of Innovative Hybrid CLT-steel Shear Wall for Mid-Rise Buildings.

Preprint

This paper examines the seismic behavior of CLT-steel hybrid walls at six- and ten-story heights to increase seismic force resistance compared to a conventional wooden wall. The ultra-strong shear walls proposed in this paper are called Framing Panel Shear Walls (FPSW), which are based on a robust articulated steel frame braced with CLT board panels and steel tendons. Timber structures are well-known for their ecological benefits, as well as their excellent seismic performance, mainly due to high strength-to-weight ratio compared to steel and concrete ones, flexibility, and redundancy. However, in order to meet the requirements regarding the maximum inter-story drifts prescribed in seismic design codes, a challenging engineering problem emerges, because sufficiently resistant, rigid and ductile connections and lateral assemblies are not available for timber to meet both the technical and economical restrictions. Therefore, it is a necessity to develop strong and cost-effective timber-based lateral systems, in order to become a real alternative to mid- and high-rises, especially in seismic countries. In this investigation, the dynamic response of cross-laminated timber (CLT) combined with hollow steel profiles has been investigated in shear wall configuration. After experimental work, an investigation was also carried out into numerical modelling for simulating the cyclic behavior of a hybrid FPSW wall and the spectral modal analysis of a six- and a ten-story buildings with FPSW. A FPSW shear wall can double the capacity and stiffness.

“…Similar behavior has been found in connections of un-tensioned high-rise buildings simply because of large gravitational loads at the first stories. Indeed, recent investigations proofed significant increases in strength, stiffness and energy dissipation of components and the entire structure, which mainly has been attributed to the compression forces and frictions at the connections (Guíñez, F. et al, 2019).…”
