Analysis of Hyperbolic Paraboloid Shell Foundation

Abstract

Analysis Of Hyperbolic Paraboloid Shell Foundation The development of shell-type foundations in analysis and design has led to the understanding that shell-type foundations have more advantages compared to their conventional foundations. The result was that the hypar shell base saves up to 43.78% and 4.76% respectively on concrete and steel.

Shell foundation is considered cost-effective when heavy loads are to be carried by weak foundation soils. Because of the low bearing capcity.if we use bending members such as slabs and beams, such situations require large foundations, the bending moments and shears in them will be large and the required sections will also be large. Shells that act mostly in tension or compression will be more efficient and more economical in such situations.

However, the labor involved in shell construction (shell surface forming, steel manufacturing, supervision, etc.) in conventional foundation type will be more than necessary. Thus, one can consider the use of shells as foundations in such special situations.

However, the work involved in shell construction (shell surface forming, steel manufacturing, supervision, etc.) will be more than necessary in conventional foundation type. Thus, in such special situations the use of shells as foundations can be considered. We must note that the intensity of loads that the shells will have to carry as a foundation structure will be much larger than in the roofs.

Shell shapes commonly used in civil engineering are generally classified as rotational and translational shells in structural engineering. Rotational shells, also called as revolution shells.

Conclusion

It gives the minimum consumption of materials over conventional footing. It gives greater load capacity and stability over conventional base. The development of shell-type foundations in analysis and design has led to the understanding that shell-type foundations have more advantages compared to their conventional foundations. The result was that the hypar shell base saves up to 43.78% and 4.76% respectively on concrete and steel.
