Chapter 9: Stress Transformation concepts
Chapter: Stress Transformation CHAPTER OBJECTIVES In this chapter, we will learn how to transform the stress components that are connected with one coordinate system into components associated with a different orientation. This is important because by understanding these transformation equations, you can find out the maximum normal stress and maximum shear stress at a specific […]
Soil Mechanics, Chapter-1 Composition and Particle Sizes of Soils
1.1 INTRODUCTION In this section, we learn that soils are not just simple dirt – they are complex, natural materials made up of many different components. This chapter sets the stage by explaining that soils come in various compositions and have particles of different sizes, which play a big role in how strong the soil […]

Metamorphism in Geology
Metamorphic Rocks “Meta” = Change “morph” = form (both Greek) A rock that has been changed from its original form (parent) by HEAT, PRESSURE (over a long time) to form a new rock. This occurs in the SOLID state at temperatures above ~200 degrees C and below the melting point of the rock Metamorphic rock […]

Structural Dynamics Concepts
Depending on the nature of the impact on the structure, loads are divided into static and dynamic. Loads are considered static if they change very slowly (with an infinitely small increment in time), without jolts or impacts. Dynamic loads are those that can change their magnitude, direction or position in relatively short periods of time. […]

Earthquakes
What is an Earthquake? An earthquake is the vibration, produced by a rapid release of seismic earth.
SAP2000 Graphic interface
In this class, we will explore the SAP2000 software, start it, observe how it loads, examine its interface after loading, and cover a few more aspects. Loading Screen: This is how the SAP2000 looks while it’s loading: The first window that appears after loading: To begin, click on ‘New Model’ from the Toolbar or Menu […]
