💫GENERAL KNOWLEDGE ON CONSTRUCTION
41. A cantilever beam is fixed at one end and free at the other.
42. Fixed-end moments are moments developed at fixed supports.
43. Bending stress in a beam is calculated using the formula σ = My/I.
44. Torsion in beams is caused by twisting moments or torques.
45. A simply supported beam has supports at both ends.
46. The moment of inertia of a rectangular section is bd³/12.
47. Deflection in beams can be calculated using integration methods.
48. Reinforcement bars should be free of rust and other contaminants.
49. Development length is the length required to transfer stress to concrete.
50. Hooked bars are used to anchor reinforcement in concrete.
51. A truss is a structure composed of members arranged in triangles.
52. Load-bearing walls transfer loads from floors and roofs to foundations.
53. Shear walls resist lateral forces such as wind and earthquakes.
54. Moment-resisting frames provide lateral stability to structures.
55. Expansion joints allow for thermal expansion and contraction in structures.
56. Pre-tensioning and post-tensioning are methods of prestressing concrete.
57. Masonry walls can be constructed using bricks, blocks, or stones.
58. Mortar is a mixture of cement, sand, and water used in masonry.
59. The typical thickness of a residential slab is 125mm.
60. The minimum reinforcement in slabs is 0.12% of the cross-sectional area.
