Rcc Roof Beam Design

Here l ef is the effective span.

Rcc roof beam design.

For beams the concrete only works in compression over a rectangular stress block above the n a. Design for shear contd pdf unavailable. Assume 50 ksi steel. 2 thick brick tile.

Determination of loads and moments on rcc lintel beam the triangular design load coming over the lintel beam can be calculated by the formula. Design of doubly reinforced beam flexure ii. The design of concrete beam includes the estimation of cross section dimension and reinforcement area to resist applied loads. There is a nominal strength that is reduced by a factor which must exceed the factored design stress.

There are two approaches for the design of beams. Design of steel structures prof. Limit state of collapse shear. From elastic calculation and the.

Design of doubly reinforced beam flexure. Slabs s1 and s2 to be designed. Construction of rcc design from start to end in step by step manner. Here we have a wood framed gable roof.

Beams resist compression and tensile forces and add rigidity to the structure. Concrete compressive strength fc 3 ksi. Let s consider a basic gable wood roof framing design. Firstly begin the design by selecting depth and width of the beam then compute reinforcement area.

The image below shows a cross section of our simple 12 x 13 house from the joist span tables section of this tutorial. Floor beam span tables of residential structural design we will now look at roof rafter and beam design. Beams generally carry vertical gravitational forces but can also be used to carry horizontal loads i e loads due to an earthquake or wind. Live load 40 psf figure 1.

Design the roof slab beam and column of house given in figure 1. Continuing on from part 3. Steel yield strength fy 40 ksi. Secondly assume reinforcement area then calculate cross section sizes.

Design of doubly reinforced beam flexure i. Reinforced concrete beam members strength design for beams sstrength design method is similar to lrfd.
