Connections

In steel structures, connections are the members that join two or more steel members. The connections are the most important members of any steel structure, and hence, they are designed more carefully. The majority of the construction cost of steel structures is incurred due to the connections. The design of connections is done as per the recommendations and specifications of the American Institute of Steel Construction (AISC).

A high-density polyethelene (HDPE) [E = 780 MPa; v = 0.46] rod has a diameter of 90 mm before load P is applied. In order to maintain certain clearances, the diameter of the rod must not exceed 92 mm when loaded. What is the largest permissible compressive load P that can be applied to the HDPE rod? P High-density polyethelene (HDPE) rod Answer: P = i kN

The point loads are placed at the fixed positions shown in the figure and they are live loads. A k a b a b dn = 1₂ Icr= M B 7 Ast Stress profile (concrete) Cross section before cracking Aso Cross section Asc Ast N.A. Q2) Now, the live load increases gradually and the moment at the critical section just exceeds the cracking moment (Mcr), but the compressive section of the concrete is still under the linear elastic region. Please be reminded that in the flexural design, the crack of the concrete section starts where the tensile stress reaches the tensile strength. It is assumed that the cracks then propagate rapidly up to the entire tension section (up to the neutral axis) and this cracked concrete section cannot resist the tension. It should be noted that in reality, concrete sections between the primary cracks can still resist some tensile stresses as shown in the figure, which should be considered in the displacement design. However, in flexure design, we design the critical section…
A composite drive shaft is made up of two sections: a solid steel core and a brass tube encasing the core. The steel core has a diameter of 80 millimeters, and the brass tube has a diameter of 100 millimeters. The maximum allowable shear stress for the steel is 100 megapascals (MPa), and for the brass, it is 50 MPa. What is the greatest torque (T) that can be safely applied to the shaft without exceeding the allowable shear stress in either material? 50 mm Brass 50 mm 40 mm Steel
