What is the difference between flat slab and flat plate?

♻️Flat slab is one with either drop panel or column capital(or both at the same time) that helps reduce shear stress on the column slab junction. On the other hand flat plates are slabs systems with the slab connected to the column directly.

What is the difference in the direct design method and the equivalent frame method for the design of flat slab?

2) Both Direct design method and Equivalent frame method are approximate methods but results obtained from Equivalent frame method are more accurate. 3) The equivalent frame method is not satisfactory for hand calculations. Therefore, use of computers software which based on Finite Element Analysis is adopted.

What is flat slab design?

Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called ‘drop panels’.

What is Direct Design Method?

The direct design method is an analytical approach by which the required area of reinforcement for short reinforced concrete columns or shear walls is determined directly without using an interaction diagram. A design diagram shows all possible fitted sections for a particular column or shear wall.

What is the difference between flat and plate?

2. Describe one basic difference between the plate and flat bar from the descriptions above. Plate is used for durability and strength and flat bar can be used in ornamental fabrication which does not require strength attributes and can also be fabricated into structural I Beams if its more than . 250” thick.

What is difference between flat and slab?

The main difference between flat slab & conventional slab-beam system is that the one is directly supported on the column while another system has a beam for support. In conventional slab-beam system, the load is transferred from slab to beam and ultimately beam to the column.

What are limitations of direct design method for designing of flat slab?

Limitations of Direct Design Method

• There must be at least three continuous spans in each direction.
• Panels should be rectangular and the ratio of longer/ shorter spans within the panel must not exceed 2 otherwise one-way actions will prevail.

What are the methods of design of flat slab?

There are two methods of analysis of RC flat slab viz. Direct Design Method and Equivalent Frame Method.

What is flat plate slab?

The flat plate is a two-way reinforced concrete framing system utilizing a slab of uniform thickness, the simplest of structural shapes. The flat slab is a two-way reinforced structural system that includes either drop panels or column capitals at columns to resist heavier loads and thus permit longer spans.

What is the difference between flat slab and solid slab?

The main difference between the two types is “drop beam”. A solid slab has drop beams whereas a flat slab has no drop beams, as a result the main problem with flat slabs is the “punching Shear” from the columns.

What is Direct design method for slab?

The direct design method (DDM) ACI Code 8.10 is an approximate procedure for the analysis and design of two-way slabs. It is limited to slab systems subjected to uniformly distribution loads and supported on equally or nearly spaced columns.

What is flat plate?

A flat plate floor system is a reinforced concrete frame system with a uniform thickness that is supported directly over the columns or the load-bearing walls. The flat plate floor system is a common floor construction type employed in the construction of the building.

What is a flat plate slab?

The flat plate is a two-way reinforced concrete framing system utilizing a slab of uniform thickness, the simplest of structural shapes. The flat slab is a two-way reinforced structural system that includes either drop panels or column capitals at columns to resist heavier loads and thus permit longer spans. Keywords:

What are the methods of designing flat slabs?

Multitudes of process and methods are involved in designing flat slabs and evaluating these slabs in flexures. Some of these methods are as following: For smaller frames, empirical methods are used but sub-frame method is used in case of more irregular frames.

What are the advantages and disadvantages of flat slab?

Thickness of flat slab is another very attractive benefit because thin slab provides the advantage of increased floor to ceiling height and lower cladding cost for the owner. However, there is profound lower limit to thickness of slab because extra reinforcements are needed to tackle design issues.

What is the difference between drop panel and flat slab?

Usually the height of drop panels is about two times the height of slab. Flat Slabs are considered suitable for most of the construction and for asymmetrical column layouts like floors with curved shapes and ramps etc.
