Beirut Arab University Dept. of Civil Engineering CVLE 423: Steel Design (I) FALL 2015-2016 Assignment #5 Due: November 30 -2015

Problem 1

Compute the maximum factored load that can be applied to this connection if designed as a bearing-type connection.

- M20 Bolts(N-Type) - Grade 8.8 - Plates St 37 - Gas-cut edges.

Problem 2

Design and detail (sketch) this double-lap splice connection for a factored load of 80 tons. Use a bolted bearing-type connection - St37- 20mm Bolts .

Problem 3 For the shown truss, design and sketch the two circled connections (A

and B) as a bearing-type connections using a single row of bolts, (5/8)” – A325-X. Assume all web members are composed of single angles (4x4x5/8) – 1/2” gusset plate. Problem4

For the bearing-type connection shown in the figure below, determine how many M22 bolts (Gr8.8) are required. Assume that the bolts threads are in the plane of shear and bearing strength is controlled by the upper limit of 2.4dtFu.
