BASIC KNOWLEDGE OF CIVIL ENGINEERING PART 2

One yard =3 feet

Concrete cube is filled in 3 layers

Slum cone is filled in 4 layes

Minimum thickness of shear wall =125 mm

Maximum thickness of shear wall =400mm

Minimum Percentage of steel in 

                                            Coloum   ={0.8℅ of                                                                  cross area}

Maximum percentage of steel in 

                                           Coloum   ={8% of                                                                  cross area}

Noimnal cover 

                 Footing   = 50mm

                 Coloum   =40mm

                 Beam       = 25mm

                 Slab          =20mm

Angle stair case      =25° to 40°

Short column fail in crushing

Long coloum fail in buklying
