Thumb Rule Average Steel In Rcc Slab

July 10,2019

The approximate steel consumption per sq.Ft built up area bua is 4 kg per sqft for low rise construction i., less than 4 floors of construction.Steel contributes the most among all individual materials, about 25 of total material cost.So, a price rise of rs.5 per kg can make big difference in the total cost of construction.

Concrete Basics In Construction From Construction

Rebar is central to reinforced concrete, so a basic understanding helps.The various sizes are important to know a 3 bar is 38 in diameter, a 7 bar is 78 in diameter, etc.The easy rule of thumb for rebar sizes is to take the rebar size and divide by 8 for the diameter in inches.

Rough Calculation For Manpower Requirement

I am pranav patil, recently i have faced one interview.They asked me to calculate manpower required for a building rcc work whereas building has 4000 sqm built up area for each floor.Total floors are 30 nos.Scheduled completion is 15 month.I calculated manpower requirement as follows.Please suggest me if i wrong.Of floors - 30 nos.

Calculating The Load Bearing Capacity Of Concrete

The reason why is fairly simple when your roof slab was constructed contractors generally did not use deformed steel reinforcing bars as they do use today.If fact, the steel rebar or wire mesh that must likely was used in your slab most likely has smooth surfaces, not deformed, thereby allowing much less bonding between the concrete and steel.

Concrete Footing Size Rule Of Thumb

A good rule of thumb is to order an extra 5 percent rounded up to the next 14 yd.Waffle slab-concrete slab with reinforcing ribs in two directions.When specifying a restrained footing, you must assure yourself that the final force required to provide the restraint can actually be developed by the restraining construction.

Civil Engineering Thumb Rules In Building Construction

Remember, thumb rules never give the accurate results, but you can use them for approximate results.There are many thumb rules which we apply in construction.Here i am discussing the most frequently used thumb rules on site.Thumb rules used in the construction by civil engineering thumb rule for shuttering work.

How Many Kg Of Steel Reinforcement In One Cubic

Well , reinforcement steel required for slab is nearly 0.8 of the volume of concrete so if concrete is 1 cum then steel will be 10.007 but density of steel is 7850 kg cum so 0.

How Many Steel Is Require In One Sqft Area

The steel is required as per the type of structure, that means the tentative calculation of steel is as per below, for foundation slab 80kgcu.For column 100 kgcu.For beam 120 kgcu.Quantity is rcc quantity of structure.

Minimum Standards For Structural Design Rcc

Minimum thickness of rcc slab i recommend is 5 125mm because a slab may contain electrical pipes embedded into them which could be 0.5 or more for internal wiring, which effectively reduces slab depths at certain places, causing cracking, weakening and water leakage during rains.So, a minimum thickness of 5 should be maintained.
