Long-Span CLT-Glulam Composite Flooring System Connected with Bamboo-Based Shear Connectors: Feasibility of Design for Assembly
Composite flooring systems built with CLT-glulam ribs have a higher strength-to-weight ratio compared to the concrete-steel composites; thus, it can result in an economical solution for spans over 12 m. In practice, the lack of studies on the structural performance of such CLT-glulam composites often leads to the oversize of the floor members. In addition, shear connectors design is crucial and drives to the structural efficiency of the floor assembly. In this paper, the long-span CLT-glulam composite flooring system is assembled using bamboo-based shear connectors. Similar to conventional mortise-tenon joints, this new connection method can minimize the required number of connectors and installation time. Modular design is incorporated in the flooring system, serving the North American mass timber construction market. The design method of the flooring system is based on the theory of composite beams with partial interaction. Design assumptions covering effective width, joint efficiency, and components configuration are discussed under ultimate limit state and serviceability limit states. Four bamboo-based shear connector prototypes with different tenon profiles are given. The optimized timber components and connectors for a 12-m span floor are implemented. Individual load-slip response of bamboo-based shear connectors is investigated by means of modeling each component with a solid-type finite element (FE) model. Results show that bamboo-based shear connectors have high stiffness values and can transfer shear force between the timber members efficiently. Based on the stress distribution analysis, discussion on the mechanical behavior and floor’s bending resistance is also included. Compared to common hardwood shear keys, bamboo connectors have advantages in terms of material and structural efficiency.
