#### THE USE OF ORION SOFTWARE FOR THE DESIGN OF REINFORCED CONCRETE DESIGN

ABSTRACT

The objective of this study was a reinforced concrete design using orion tool for architecture students. The tool, a computer program with graphic interface, provides basic concepts for concrete structure calculations and procedures. The graphic interface is expected to help architecture students to understand the design process.

CHAPTER ONE

1.0 INTRODUCTION

In the design and analysis of reinforced concrete members, you are presented with a problem unfamiliar to most of you: “The mechanics of members consisting of two materials.” To compound this problem, one of the materials (concrete) behaves differently in tension than in compression, and may be considered to be either elastic or inelastic, if it is not neglected entirely.

Although we will encounter some peculiar aspects of behavior of concrete members, we will usually be close to a solution for most problems if we can apply the following three basic ideas:

• Geometry of deformation of sections will be consistent under given types of loading; i.e., moment will always cause strain to vary linearly with distance from neutral axis, etc.

• Mechanics of materials will allow us to relate stresses to strains.

• Sections will be in equilibrium: external moments will be resisted by internal moment, external axial load will be equal to the sum of internal axial forces. (Many new engineers overly impressed speed and apparent accuracy of modern structural analysis computational procedures think less about equilibrium and details).
