In this article, guidance is provided on selecting locations and sizes for openings in two-way slabs for both new and existing structures.
Detailing of Concrete Slab Openings (Cutouts)
In reinforced concrete construction, openings (also called cutouts) in slabs are often necessary to accommodate elements like lifts, ducts, cables, or other utilities that need to pass from one floor to another, especially in industrial buildings.These openings, while essential, introduce unique challenges in terms of structural integrity. As such, special care must be taken when detailing the ...
Reinforcement Detailing of Concrete Slab Openings (Cutouts)
Many times openings (cutouts) are required to be provided in reinforced concrete slab in buildings to provide way for lifts, or cables, ducts or other instrument to pass through one floor to other floors, mainly in the case of industrial ...
Openings in slabs are usually required for plumbing, fire protection pipes, heat and ventilation ducts and air conditioning. Larger openings that could amount to the elimination of a large area within a slab panel are sometimes required for stairs and elevators shafts.
Openings in Slabs - The Structural World
2018年6月1日 · Openings in the slab system can be found on Section 8.5.4 of ACI 318M-14. This states that “ Openings of any size shall be permitted in the slab system is shown by analysis that all strength and serviceability requirements, including the limits on deflections, are satisfied”. How to Calculate the Extra Bars along Slab Openings?
An Engineer's Guide to: Openings in Concrete Floor - studylib.net
Although all multistory buildings require multiple small slab penetrations for routing of plumbing, fire protection piping, and ductwork between floors and larger openings for stairwells and elevator shafts, your course probably covered the topic of slab openings only briefly (if at all).

Openings in slabs are usually required for plumbing, fire protection pipes, heat and ventilation ducts and air conditioning. Larger openings that could amount to the elimination of a large area within a slab panel are sometimes required for stairs and elevators shafts.
Sometimes it is necessary to create large openings in a slab for stairwells or large duct shafts between floors. Creating a large opening in a PT slab will result in several PT strands being interrupted by the new opening. An engineer should be consulted to analyze the effect that the new opening will have on the slab.
The effect of openings (vertical holes through slabs) on the shear strength of slabs must be investigated when the openings are within the column strip areas of slabs or within middle strip areas when the openings are closer than
