Design of a singly reinforced concrete beam as per IS 456:2000

Image
Design of a singly reinforced concrete beam Example: Design of a singly reinforced concrete beam for the following data.           Clear Span of the beam – 3 m           Width of supports – 200 mm           Working live load – 6 KN/m           Grade of concrete – M20           Grade of steel – Fe-415 HYSD bars Solution: Given Data –   f ck  = 20 N/mm 2 .                         f y    = 415 N/mm 2 .                                                 Load factor = 1...

Classification of columns

Image
  Types of columns & their properties Structural Concrete member in compression are generally termed as columns & strut. The term column is used for structural member transferring loads to the ground. As per Indian Standard Code IS 456:2000 clause 25.1.1 defines the column as a compression member whose effective length exceeds three times the least lateral dimension. Whereas pedestal is termed as vertical compression members whose effective length is less than three times its least lateral dimension. Axially loaded columns may fail in any one of the following modes: Pure Compression failure- Where the column generally fails due to the axial load & Buldge at the center of the unsupported length. Combined Compression & bending failure- Where the column generally fails due to the combined effect of axial load & bending due to the presence of beams.   Failure by elastic instability. These modes generally depend on the slenderness ratio of ...

Waterproof coating & membrane

Image
What is waterproof coating & membrane To prevent the entry of water through seepage or moisture damp inside an RCC structure waterproofing is used. Generally, after completion of construction work of a structure waterproofing work is carried out. The process of waterproofing can be carried out in many ways. However, it can be broadly classified as:   Coating – By the use of Polyurea coating as a waterproofing membrane.   Membrane - By using the waterproofing membrane. Waterproofing coat (PU): Surface Preparation – The surface is inspected for any structural defects such as cracks, undulations, and honeycombs if found it shall be rectified before coating. Right angle junctions between slab & perpendicular wall/column shall be treated by coving the junction (75mm x 75mm generally) & filling it with a polymer-modified mortar. The surface shall be free from dust, loose materials, cracks & in saturated surface dry (SSD) condition before the applica...
