Concrete & Steel Structures
Concrete & Steel Structures for GATE Civil Engineering, one topic per lesson: the theory in plain words, the formulas, a solved example, and GATE-style questions (MCQ, MSQ and NAT) whose numerical answers are recomputed by a program when the site is built.
1Concrete
- Concrete Technology and Material PropertiesCement types and tests, aggregates, water-cement ratio and Abrams' law, workability tests, mix design basics, characteristic strength, modulus of elasticity, creep and shrinkage.
- Limit State Design of Beams in FlexureLimit state method, partial safety factors, stress block, neutral axis depth, balanced, under- and over-reinforced sections, moment of resistance, doubly reinforced and flanged beams.
- Shear, Bond, Slabs, Columns and FootingsNominal shear stress and shear reinforcement, development length, one-way and two-way slabs, short and slender columns, minimum eccentricity, and design checks for isolated footings.
- Prestressed ConcretePrinciples of prestressing, pre-tensioning and post-tensioning, stress concept and load balancing, stresses at transfer and service, and losses of prestress with formulas.
