| Abstract This paper examines the seismic behavior of CLT-steel hybrid walls at 6- and 10-story heights to increase seismic force resistance compared to conventional wooden walls. 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 benefts, as well as their excellent seismic performance, mainly due to the high strength-to-weight ratio compared to steel and concrete ones, fexibility, 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 sufciently resistant, rigid and ductile connections and lateral assemblies are not available for timber to meet both the technical and economical restrictions. Therefore, it is necessary to develop strong and cost-efective 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 profles has been investigated in shear wall confguration. After experimental work, research was also carried out into numerical modelling for simulating the cyclic behavior of a hybrid FPSW wall and the spectral modal analysis of buildings of 6- and a 10-stories with FPSW. A FPSW shear wall can double the capacity and stifness. Introduction In some seismic-prone countries, such as Chile, typical wood shear wall confgurations may not have enough vertical strength for mid- and high-rise timber buildings. In Chile, the structural design standard (Instituto Nacional de Normalización 2009) was developed in timber constructions for low-rise buildings. Currently, there are two predominant structural systems are used in the world for wood construction: platform frame construction using light-frame timber building (LFTB) and cross laminated timber (CLT) construction.Nowadays, mid-height timber buildings are designed using the American Wood Council (2015) standard for the USA and EN 1995-1-1:2004+A2:2014 (2014) as the European Standard. The Chilean code for seismic design of buildings, NCh433 (Instituto Nacional de Normalización 2009) defnes seismic response reduction factors (R) to reduce the elastic design forces due to the capacity of the structure to dissipate energy during an earthquake. |
