panels. In this example, the latter option will be used to achieve better understanding for the design of two-way slab with drop panels often called flat slab. Check the drop panel dimensional limitations as follows: 1) The drop panel shall project below the slab at least one-fourth of the adjacent slab thickness. ACI 318-14 (8.2.4(a)) Deflection is a function of the stiffness of the slab as a measure of its thickness, a minimum thickness has to be provided irrespective of the flexural thickness requirement. Table 9.5(c) of ACI gives the minimum thickness of slabs without interior beams.

What is column capital & drop panel? Uses of column heads (capital): ⋅ Shear strength of flat slab is increased by using column heads. ⋅ Column heads reduce the clear or effective span, and therefore, reduce the moment in the flat slab floor. Uses of drop panels: ⋅ Drop panels increase the shear strength of flat slab floor. The total thickness including the slab and the drop panel (h) = h s + h dp = 220 + 57 = 277 mm Nominal Lumber Size, mm Actual Lumber Size, mm Plyform Thickness, mm h dp, mm 2x 38 19 57 4x 89 19 108 Figure 5 - Drop Panel Formwork Details 2) Drop panel size: 0.6 /1,000 2 ny 30 d s n lf x h l CSA A23.3-14 (13.2.4) Rearrange the previous equation drop panels and it is usually suited for lightly loaded floors with short spans typically for residential and hotel buildings. The lateral loads are independently resisted by shear walls. The two design procedures shown in ACI 318-14: Direct Design Method (DDM) and the Equivalent Frame Method (EFM) are illustrated in detail in this example. This example highlights code based selection of drop panel dimensions, analysis process of non-prismatic slab with drop panels, the crucial role of drop panels in resisting two-way shear at columns, and detailed deflection calculations.

Two-Way Flat Slab (Concrete Floor with Drop Panels) System Analysis and Design (ACI 318-14) Two-Way Flat Slab (Concrete Floor with Drop Panels) System Analysis and Design (ACI 318-14) (A) Depth of the drop panel must be at least ¼ of the slab thickness away from the drop panel; and (B) The drop panel must extend 1/6 of the span length from the center of support in each direction 1. In this video, you can get a clear knowledge about the Flat slab and why it is preferable by many. Also, this video contains how to design a Flat slab wit. (beam) shear at the edge of the drop panel (Section 11.3.1). As a simplification of the forming, if possible, the slab dimension between the drop panels should be an even multiple of 2 ft and preferably of 4 ft. If the span is not an even multiple in feet, it will usually be preferable to add the few odd inches to the drop panel dimension.

Design of Reinforced Concrete Flat Slab with Drop Panel. Mahmoud SAYED AHMED. This educational solved example for the design of reinforced concrete flat slab with drop panel, and check for punching shear. The reinforcement for the column strip was design for the direction from East-to-West only. See Full PDF. What is a Drop panel A drop panel is similar in nature to a shear cap, however its plan dimension is larger. A drop panel is a projection below the slab used to reduce the amount of negative reinforcement over a column or the minimum required slab thickness, and to increase the slab shear strength.
