## Complex Geometries – Stable Feature Behind MSE Wall

Stable Feature Behind MSE Wall / Narrow Wall This will be one of several  posts regarding MSE walls with complex geometry. The main references for this post and the posts to follow will be the research conducted by The Federal Highway Administration (FHWA) and mainly…

## Torsion in Rectangular Prism

Torsion in Rectangular Prism I hope to expand on this post in the future and relate the equations that are derived for find stresses and strains of a rectangular prism (bar) to that of an I shaped section. Then relating…

## Mechanics of Materials – Basics

Mechanics of Materials – Basics I would like to describe the process or logic or algorithm if you will in which must be followed in order to develop theories for mechanics of materials.  The process / logic / algorithm can go in…

## Stability – AISC’s Approximate Second-Order Analysis B1 B2 Method

AISC’s Approximate Second-Order Analysis B1 B2 Method Lets look at a very simple building with a simple moment frame to resist lateral loads. We will complete the analysis using AISC’s approximate second-order analysis more commonly known as the B1 – B2…

## Portal Method – Moments and Deflection

Portal Method – Moments and Deflection The portal method is an analysis method for used for finding approximate internal forces in indeterminate structures subject to a lateral load. Portal Frame Assumptions: Zero moment at the center of each girder. Therefore…

## Stability – AISC’s Direct Analysis Method

Stability – AISC’s Direct Analysis Method Intro In the 14th Edition of the American Steel Construction Manual the Direct Analysis Method (DAM) is moved into the main specification from the appendix. I know many are not used to this new…

## Surcharge Analysis – Elastic Methods – Strip Load

Strip Load Surcharge Analysis using Elastic Methods UPDATED – Problem Solved… Here we will dig deeper into analyzing strip loads with elastic methods. First to avoid confusion between seeing similar equations which use different reference angles, we will set our own nomenclature.…
