US3916635A - Piling and method of installation - Google

A ''''''''cast-in-place'''''''' thin-walled piling, wherein the thin-walled tubular casing shell is connected to a precast reinforced concrete driving base by being outwardly expanded at its leading end so as to form a friction fit within a tapered socket formed in the base while the piling is simultaneously driven into place. An internal drop hammer compacts a charge of concrete within the casing

Introduction to Shell Structures

•Definition: • A shell is a thin structure composed of curved sheets of material, so that the curvature plays an important role in the structural behavior, realizing a spatial form • Motivation: • A shell is the most efficient way of using the material, and can be very useful in case o storage of fluids and solids (uniform loads)

Weight bearing - Physiopedia

In orthopaedics, weight bearing refers to how much weight a person puts through an injured body part. During single leg stance, an aulatory person with no physical limitations will carry 100% of their body weight through each leg. Thus, grades of weight bearing are generally expressed as a percent or portion of this nuer. The concept of prescribing weight bearing …
