Span/ depth ratios for concrete beams and slabs In CP110, basic span/effective depth ratios are still quoted (Tables 8 and 9) but these are then modified by an array of factors that relate to steel stress and quantity . The values for continuous slabs are based on moments from CP114 Table 15, and those for two-way slabs and flat slabs are based on moments from CP110 

Analysis and Design of Slabs "One Way" - Civil Engineers PK Two edge supported slab is always one-way. Cantilever slab is always one-way. Main steel is only provided parallel to span; One-way slab is designed as singly reinforced rectangular section. h(min) for the slab is different compared with the beams.

The Design of Reinforced Concrete Slabs - INTI Reinforced concrete floor systems provide an economical solution for virtually any span and loading condition. Page 3. Introduction. Selecting the most effective floor system can be vital to achieving overall economy, For non-prestressed, two-way slabs, minimum thickness requirements are given in Section. 9.5.3.

Designing a Continuous One Way Reinforced Concrete Slab per The first step is to find the total slab thickness, h, with the aid of Table 9.5(a) in ACI Code 318-11. This table gives guidance on the minimum thickness of nonprestressed beams or one-way slabs. We consider two cases for this calculation: exterior/edge span, interior span. The exterior span has one
