About Me


Hello,

My name is Avirup, I am a B.Tech Graduate in Civil Engineering.
Different day at job in engineering field brings a new type of challenge, I will shared all my experiences in this blog.

Concrete Mix Design M25 SCC [IS CODE]

In order to determine the mix design quantities of different ingredients for a particular grade of concrete, few steps are required which are as follows: 1.        Determine the target compressive strength The target compressive strength can be calculated by the following formula                                 T fck = T cs + 1.65 SD ……… [IS CODE: 10262-2009]                  Where, T fck is the target compressive strength of concrete.                              T cs is the compressive strength of concrete.            ...

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 ...
