Question

Which of the following loads are not considered in the design of gantry girders?

(a) longitudinal loads

(b) gravity loads

(c) lateral loads

(d) wind loads

I have been asked this question during an internship interview.

The origin of the question is Gantry Girders & Design of Industrial Buildings topic in chapter Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer 1

The correct option is (d) wind loads

To explain I would say: The loads considered in the design of gantry girders are vertical loads or gravity loads, longitudinal loads, lateral loads and impact loads. The vertical force is the reaction from crane girder, acting vertically downward. The longitudinal thrust is due to starting and stopping of crane acting in longitudinal direction. The lateral thrust is due to starting and stopping of the crab acting horizontally normal to the gantry girder.
