INVESTIGATION OF STEEL COLUMN BASE PLATE UNDER MULTIAXIAL LOADING CONDITIONS

Abstract

A technique is developed in this research which permits the derivation of the volume of the base of the column under the uniaxial and bi-axial combination of the forces. The process of obtaining a column base stiffness under an axis which is considered weak, bending is obtained by changing the structural path that already exists to fit such loading. The curve at the contact is formed using the major axis bending resistance. The model is built on software that was integrated with the base plate, column and base. Basically, two things were used i.e. concrete and steel. Subsequently these materials are combined together to form a single model using the mode. This model is provided by a set of standard conditions called Encastre in software where all six levels of freedom are limited. The luggage is then placed in a vertical model with a vertical seating or integrated load. This loading is placed in the column and its reaction to the metal plate and the concrete base is noted. The contact area is built between the two surfaces because the conditions only cover the arms but do not form any interaction between them. For this purpose, two types of land are used, one is called a bounded arch and the other is called an earth working tool which is also assigned a shooting factor of 0.3. For the accuracy of the results, all model items are transported and their size is as small as 0.04.
