How to compute steel for triangular slab

In this construction video tutorial, you can find the detailed process for estimating steel for the slabs which are constructed in triangular shapes. The process is simple and straight forward. Initially you have to discover the cutting length for each bar and then total weight of bars necessary for triangular slab. There are six types […]

Waffle Slab Cross Section and it’s Reinforcement Details

Waffle slab is something connected with the ribbed floors. They are consisting of equally spaced ribs  usually supported directly with the columns. They are either one-way spanning systems (known as ribbed slab) or a two-way ribbed system (waffle slab). The reinforced concrete waffle slab (ribbed slab) cross section reinforcement detail comprises ribbing (beams) reinforcement, slab […]


In high rise buildings and skyscrapers, thinner, pre-cast concrete slabs are slung between the steel frames to form the floors and ceilings on each level. On the technical drawings, reinforced concrete slabs are often abbreviated to “r.c.c.slab” or simply “r.c.”. A Reinforced Concrete Slab is one of the most important structural elements of modern buildings. […]

Sandwich-voided slabs

In reality, sandwich-voided slabs are ribbed slabs with a slab placed both on their upper and lower surface. Sandwich slabs may have the disadvantage of a larger weight compared to the ribbed ones but on the other hand, they have the advantage that their spans and supports behave in the same proper way. Their construction […]
