Deep Foundation: Introduction of Pile Foundation
In situations where the soil is poor at shallow depth, in such case safely transfer the load at suitable depth…
Properties of Soil
Soil is three phase system that consists of solid, liquid and gas that do not occupy separate volume and are…
Determine the position of neutral axis for the given section.
b) if instead of fe250 of grade of steel fe 415 used then compute the depth of N/A using following relationships.
Calculate MoR (Moment of Resistance) of the given section.
a) Ast = 3-25 dia
b) Ast = 8-25 dia
c) Ast,lim
A rectangular under r/f section is effective size 300mm X 450 mm is r/f with 3-16 dia & fe415, M20 concrete. Assume straight line instead parabola for stress-strain curve of concrete & partial FOS = 1 Compute:
1. Position of N/A wrt extreme compression fibre.
2. Calculate difference between depth N/A calculated as per IS456 and part a.
In design of beam by LSM in flexure as per IS456, let max strain limited to 0.0025. For the situation consider a rectangular section of effective size (250X350)mm, Ast =1500 mm2 , Fe250 and M30, Calculate
a. Position of NA for Balanced Section.
b. At the Limit state of collapse of flexure, Calculate the force on compression zone of section.
The stress and strain curve of concrete is given, find the MOR of cross-section if partial FOS = 1.15. (B=350 mm, d = 700 mm, Eff. Cover =50 mm, 4-25 dia)
Design Critical Section of RCC beam of overall size (350mm x 750 mm) subjected to live load of 30 KN/m over an effective simply supported span of 6m. Consider effective cover of 50mm, Use M20 Grade of concrete and fe415 steel.
Design a singly Supported reinforced rectangular section for service bending Moment of 200 KN-m, Use M25, Fe415, Provide effective cover of 50mm.
