Compression Members

Two steel columns $$P$$ (Length $$L$$ and yield strength $${f_y} = 250\,\,MPa$$) and $$Q$$ (length $$2L$$ and yield strength $${f_y} = 500\,\,MPa$$) have the same cross-sections and end-conditions. The ratio of buckling...

The square root of the ratio of moment of inertia of the cross-section to its cross-sectional area is called

Consider the following statements for a compression member $${\rm I}.\,\,\,\,$$ The elastic critical stress in compression increases with decrease in slenderness ratio $${\rm II}.\,\,\,\,$$ The effective length depends o...

Consider the following statements $${\rm I}.\,\,\,\,$$ Effective length of a battened column is usually increased to account for the additional load on battens due to the lateral expansion of columns. $${\rm II}.\,\,\,\,...

A strut in a steel truss is composed of two equal angles $$ISA$$ $$150mm \times 150mm$$ of thickness $$100$$ $$mm$$ connected back-to back to the same side of a gusset plate. The cross sectional area of each angle is $$2...

In the design of lacing system for a, built-up steel column, the maximum allowable slenderness ratio of lacing bar is

Given reason for the following is not more than $$20$$ words (a) A maximum permissible distance between lacing and battens in steel columns is $$\,\,\,\,\,\,\,$$ usually specified. (b) It is sometimes preferable to have...

Consider the following two statements related to structural steel design, and identify whether they are True or FALSE. $${\rm I}.\,\,\,\,\,\,$$ The Euler buckling load of a slender steel column depends on the yield stren...
