It is a must to design the structure for the loads that applied when it is used.

Reduction in the live load can not be done for any reason. Use Alternative LoadingĪpplied on the structural elements affects the deflection of the slab or beam. Therefore, with the increase of the section height, stiffness increases, and as a result, deflection reduces.Ī similar type concept is applied for the slabs too. Here “I” is the second-moment of the area of the beam. Stiffness of beam Elements propionate to EI/ L The stiffness of the structural element can be increase by increasing the depth of the element. There is no possibility to reduce the loads on the structure other than considering using modifying the weight of the nonstructural elements. Stiffness of the structural element is the key factor that affecting the deflection of the element as we can not control the applied loads on the element which we should consider in the design. Increase the Depth of the Beams and Slabs

Increase the compression reinforcements.

Increase the depth of the beams and slabs.

There are several methods that can be adopted to reduce the slab and beam deflection. Therefore, during the design, it is required to control the deflection of slabs. If not, slabs and beams will crack due to the excessive deflections.įurther, an increase in the deflections in the beams and slabs could lead to damaging the nonstructural members such as partition walls, claddings connected to the structure, ceilings, etc.

Beam and slab deflection needs to control as serviceability requirements.
