| 摘要 |
The present invention concerns a framing system for a composite concrete floor, the framing system comprising horizontally extending primary framing members supporting secondary framing members across the primary framing members. Each of the secondary framing members has two opposite ends provided with a shear shoe fixed to the primary framing members by means of a structural joint sufficient to provide a shear connection between the concrete floor and the primary framing members. Thanks to these shear shoes, the framing system of the invention has an increased resistance to horizontal shear forces as compared to prior art concrete floor systems.
