Evaluation of averaged mechanical property of timoshenko beams with microstructures

Abstract

Some kinds of element test are generally conducted in order to evaluate mechanical characteristics of structural members that have complex microstructures such as steel and concrete composite beams. However, the element test with a part of the structural member can not faithfully reconstruct deformation state in actual structures. To that end, we formulate a beam with averaged mechanical properties in order to evaluate mechanical properties of three dimensional Timoshenko beams with microstructures.
