Staff Selection Commission (SSC) Recruitment 2012
Structural Engineering
Theory of structures:
Elasticity constants, types of beams - determinate and
indeterminate, bending moment and shear force diagrams of simply supported, cantilever
and over hanging beams. Moment of area and moment of inertia for rectangular & circular
sections, bending moment and shear stress for tee, channel and compound sections,
chimneys, dams and retaining walls, eccentric loads, slope deflection of simply supported
and cantilever beams, critical load and columns, Torsion of circular section.
Concrete Technology: Properties, Advantages and uses of concrete, cement aggregates,
importance of water quality, water cement ratio, workability, mix design, storage, batching,
mixing, placement, compaction, finishing and curing of concrete, quality control of concrete,
hot weather and cold weather concreting, repair and maintenance of concrete structures.
RCC Design: RCC beams-flexural strength, shear strength, bond strength, design of singly
reinforced and doubly reinforced beams, cantilever beams. T-beams, lintels. One way and
two way slabs, isolated footings. Reinforced brick works, columns, staircases, retaining
walls, water tanks (RCC design questions may be based on both Limit State and Working
Stress methods).
Steel Design: Steel design and construction of steel columns, beams roof trusses plate
girders.
