Development of the structural system with steel frame and wooden floor: Connection method of steel beam and wooden floor

摘要

The authors propose to replace a reinforced concrete (RC) slab with a cross-laminated timber (CLT)rnfloor panel as a method to increase the use of timber in moderate- or large-scale buildings. Thernadvantages of using CLT floor panels are as follows: 1) the weight of the building is reduced, 2) anrnenvironmental value is established, 3) forest resources are effectively utilized, and 4) there is arncontribution in solving the global environmental problem. A floor effects the enhancement ofrnflexural stiffness and strength of steel beams; hence, for a robust building structure, the authorsrnmust focus on and dynamically solve all structure performance problems. In addition, it isrnnecessary to investigate the method of connection of steel beams and CLT floor panels. Push-outrnshear tests and pure bending tests were conducted to investigate the structural performance ofrnCLT and composite steel beams. The test results indicated that the CLT and steel composite beamrnshowed good structural performance.
