Problem Statement: Design of a Canopy Connection

A canopy is intended to be built at the entrance of the building described above. The canopy will be made of suspended systems. Each system will consist of twin glulam beams (Bei) and a slotted-in sawn-timber brace (Bri)  as shown below.

Given Data:

  • Beams (Bei): [2] Glulam – SP 20f-EX (80 x 342)
  • Brace (Bri): Sawn Timber (Beams and Stringers) – D. Fir-L   Select Structural (SS) (140 x 343)
  • All wood used for the canopy’s structure is untreated and seasoned.
  • All wood on the canopy (including the connection area) is expected to get wet during the service life of the building.

Design Requirement:

The connection at point B is of interest in this assignment. At that location (point B), beam Be1 is connected to brace Br1 through 4 bolts, as described on detail B. Use the software to design the connection assuming it is subjected to a tension force Tf = 25 kN.

Select the most appropriate answers based on the software output and standard design requirements.
