reinforced concrete prise
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
The effective depth of a T-beam for heavy loads is crucial for ensuring adequate strength and stability. Typically, a larger effective depth increases the beam's moment of inertia, allowing it to better resist bending and shear forces. For heavy loads, the effective depth is often optimized based on factors such as span length, load conditions, and material properties, usually falling in the range of 0.5 to 0.75 times the span length. Ultimately, the specific value should be determined through structural analysis and design codes to ensure safety and performance.
Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.

Dasign of T- beam is some what similar to rectangular beam, in design slab thickness is determined first. the slab is acts as compression flange in designing the beam. the flange acts as compression zone, which is balance by steel embeded in the bottom web of the beam. slab thickness= t, in. effective depth= d, in. width of web= b', in. flange width= b, in. width of flange should be least of the three alternatives, 1. span/4. 2. b' + 16t. 3. centre to centre spacing of beams.

To calculate the beam spread angle in a rectangular beam transducer probe, you can use trigonometry. The beam spread angle can be calculated using the dimensions of the probe, usually the width and height of the rectangular aperture. You can use trigonometric functions like tangent or arcsine to determine the angle of beam spread based on the dimensions of the probe.
when our demand is more than capacity then designer prefers to choose doubly reinforced beam .for example your maximum moment is greater than nominal momentthen doubly reinforced beam is used.
this a type of beam which contain the depth of slab in its depth. and if you want to decrease the depth of beam then just design it again reducing the depth from 12 inch to 8 inch it will change the required area of steel and grade of concrete. thats it
to resist shear force
Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.
The vertical portion of the I-beam resists shear force better than a rectangular one. The "I" portion also deflects force because of its design.
