Reinforcement is provided ... WebWaffle slabs are often utilized as both ceiling & floor slabs. Suitable for spans of 7metres – 16metres; longer spans are additionally possible in case of post-tensioning. These systems are light in weight & therefore considerable saving is ensured within the framework because a light framework is required. Disadvantages of Waffle Slab
WebDraped post-tensioning can be designed to balance part of the gravity loads. Combining unbonded post-tensioned tendons and nonprestressed reinforcement results in reduced slab thickness. In addition, the use of nonprestressed rein- forcement supplements prestressed tendons to meet the required nominal strength and control slab cracking. … Web31 Jul 2024 · Waffle slabs are much stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs for spans longer than 40 feet (12 …
