What is the maximum vertical deflection allowed for a gantry girder where the cranes are manually operated?(a) L/500(b) L/700(c) L/600(d) L/800I got this question by my school principal while I was bunking the class.The query is from Gantry Girders & Design of Industrial Buildings in portion Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer»

Right option is (a) L/500

For explanation I would say: The vertical deflection of gantry girder where the cranes are manually operated should not exceed L/500, where L is the SPAN of gantry girder. The maximum vertical deflection allowed for a gantry girder where the cranes are travelling overhead and operated ELECTRICALLY upto 500kN is L/750 and operated electrically over 500kN is L/1000. When gantry GIRDERS carry moving LOADS such as charging cars, the deflection should not exceed L/600.
