This paper presents a simplified method to analyze and design the irregular reinforced concrete slabs based on structural safety and economy.

Nov 3, 2023 · To form curved concrete, there are several options available. These include bendyform, flexi-form, ketter forms, plastiforms, plastiform, poly forms, wood forms, metal forms, insulated concrete forms (ICFs), melamine, laminated board, acrylic glass, and form liners.

Definition: A cylindrical shell may be defined as a curved slab which has been cut form a full cylinder. The slab is bounded by two straight “longitudinal” edges parallel to the axis of the cylinder and by two curved transverse edges in planes perpendicular to the axis; the slab is curved in only one direction.

In the construction world, formwork for curved structures (both walls and slabs) entails a technical and aesthetic challenge that can completely transform the appearance and functionality of a project.

Mar 9, 2010 · I have the following curved reinforced concrete slab supported on three sides (See attached). I am trying to find a way to design the slab without being overly conservative. What would be the best way to design it?

Nov 1, 1994 · Horizontally-curved concrete waffle slab structures are sometimes used as superstructures of bridges and as floor slabs in large exhibition halls. The idealization of a horizontally-curved wide structure as a curved beam or an assemblage of curved beams leads to inaccurate results.

Jan 1, 1997 · Horizontally curved concrete slab structures are often used in bridge superstructures as well as in large auditoriums with a minimum number of supports. A method is developed to analyse and design such structures based on their ultimate load-carrying capacity.

In this paper, a curved slab with high load bearing capacity and less volume of concrete is proposed, in comparison with a conventional slab. A conventional slab is designed according to the provisions of IS 456: 2000 and the same slab is given a curved profile.

Oct 6, 2024 · The design of curved slabs involves the calculation of bending moment, area of steel reinforcement, effective depth, lever arm factor, and width. These calculations are essential to ensure the structural integrity and safety of the curved slab.

While most curved bridge structures can be designed and constructed with the precast concrete curved U-girders, the most common application has been interchange flyover ramps where aesthetics are important, the curve makes chorded girders impractical, and highways and ramps below make precast concrete construction advantageous.
