Floor Slab Thickness Design

Depending upon the type load coming upon the slab the thickness is varied.

Floor slab thickness design.

Design process includes proper assumption of structural element sizes and then check. Quality floor construction includes good subgrade compaction even thickness slabs low slump concrete straight bulkhead lines and control cuts spaced 24 to 30 times the slab thickness. The thickness of the garage floor slab depends on many factors such as types of loads coming upon the slab climatic condition design mix of the concrete and span of the concrete. Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes.

Many of these requirements are defined by the class of floor the owner wants note that decorative concrete is typically a class 1 floor. Floors are classified based on the intended use of the floor see the table below that was adapted from aci 302 1 r 04 concrete floor and slab construction. Type b slab with shri n k a g e c o n t r ol re i n f o rc e m e n t. Type b floor slabs are similar to plain concre t e s l a b s but they contain some dis t r ibuted re i n f o r cement to contro l the effects of shrinkage and temper a t u r e changes.

Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing. The design and detailing of these slabs are an involved process as the interaction between the natural and or made ground and the rigid concrete floor slab presents challenges in terms of cracking movement and flatness. What should be the thickness of concrete slabs for walls minimum thickness of concrete slab beam column foundation the structure magazine a practical design for thin composite steel concrete slab an overview sciencedirect topics solved 1 3 the second floor of a light manufacturing bui solved 1 3 the second floor of a light manufacturing bui. A typical base floor slab where the design criteria include controlling moisture migration and water vapor transmission into the interior space can be referred to as a waterproof.

For example in a high rise building an increase in the thickness of slab by 5mm result significantly increase column axial loads. Standard thickness of the garage floor slab used worldwide is 6 inches. Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented. The thickness of slab is a vital factor in the building design and construction and it directly related the cost of the structural system.
