A square steel slab base of are 1 m2 is provided for a column made of two rolled channel sections. The 300 mm 300 mm column carries an axial compressive load of 2000 kN. The line of action of the load passed through the centroid of the column section as well as of the slab base. The permissible bending stress in the slab base is 185 MPa. The required minimum thickness of the slab base is
A strut in a steel truss is composed of two equal angles ISA 150 mm 150 mm of thickness 100 mm connected back-toback to the same side of a gusset plate. The cross sectional area of each angle is 2921 mm2 and moment of inertia (Ixx = Iyy) is 6335000 mm4 . The distance of the centroid of the angle from its surface (Cx = Cy) is 40.8 mm. The minimum radius of gyration of the sturt is
ISA 100 100 10 mm (Cross sectional area = 1908 mm2) serves as tensile member. This angle is welded to a gusset plate along A and B appropriately as shown. Assuming the yield strength of the steel to be 260 N/mm2 the tensile strength of this member can be taken to be approximately.
A symmetric I-section (with width of each flange = 50 mm, thickness of each flange = 10 mm, depth of web = 100 mm and thickness of web = 10 mm) of steel is subjected to a shear force of 100 kN. Find the magnitude of the shear stress (in N/mm2) in the web at its junction with the top flange.
A steel section is subjected to a combination of shear and bending actions. The applied shear force is V and the shear capacity of the section is Vs. For such a section, high shear force (as per IS:800-2007) is defined as
Two steel columns P (length L and yield strength fy = 250 MPa) and Q (length 2L and yield strength fy = 500 MPa) have the same cross-sections and end-conditions. The ratio of buckling load of column P to that of column Q is
Consider the following statements:I. The width-thickness ratio limitations on the plate elements under compression in steel members are imposed by IS: 800-1984 in order to avoid fabrication difficulties. II. In a doubly reinforced concrete beam, the strain in compressive reinforcement is higher than the strain in the adjoining concrete.III. If a cantilever I section supports slab construction all along its length with sufficient friction between them, the permissible bending stress in compression will be the same as that in tension. The TRUE statements are
A circular solid shaft of span L = 5 m is fixed at one end and free at the other end. A twisting moment T = 100 kN - m is applied at the free end. The torsional rigidity Gj is 5000 kNm2 /red. Fllowing statements are made for this shaft.I. The maximum rotation is 0.01 rad II. The torsional strain energy is 1 kN-m With reference to the above statements, which of the following applies?
In the design of welded tension members, consider the following statements:I. The entire cross-sectional area of the connected leg is assumed to contribute to the effective area in case of angles.II. Two angles back-to-back and tack-welded as per the coda requirements may be assumed to behave as a tee section. III. A check on slenderness ratio may be necessary in some cases. The TRUE statements is/are
Consider the following statements: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. II. As per IS: 800-1984, permissible stress in bending compression depends on both Euler buckling stress and the yield stress of steel. III. As per IS: 800-1984, the effective length of a column effectively held in position at both ends but not restrained against rotation, is taken to be greater than that in the ideal end conditions. The TRUE statements are
