DISCOVERY IN NON-LINEAR THEORY APPLICATION
A sky scraper with foundation supported by piles has been difficult problems for engineers.
The Hyper STRUDL(USP) was and is based on a theoretical discovery/break-through in FINITE ELEMENT THEORY.
It was and is unpublished but the Program was completed.
A SKY SCRAPER UNDER WIND and/or SEISMIC LATERAL LOADS:
1) Piles can be modeled with different elastic moduli (for different resisting strengths) based on compression or tension.
2) Generally speaking, piles under compression, moduli of elasticity can be full strength.
3) Under tension, they are to be weaker. (See instruction on MAT.DAT for Non-linear material Property input.)
ALL SOIL UNDER FOUNDATION MAT CAN RESIST THE LATERAL LOADS:
4) A matrix of discrete ONE-way elements, which are Compression-only can be modeled in addition to the pile elements.
4-1) All soil elements can resist lateral loads under compression while under tension; zero.
4-2) The Soil Confined Modulus of Elasticity rather than simple MoE must be used in MAT.DAT(material property data).
4-3) The pile and soil elements may create in MODEL.DAT a geometric space interference. However its effect is negligible.
4-4) Thus geometric layout for the matrix of discrete soil elements can be greatly regularized.
One of Hyper STRUDL's Powerful Capabilities.
ELEMent ONE-way to model Compression-only Soil elements to reduce amount of pile requirement.
