Analysis of Offset Surcharges on Retaining Walls Using Elastic Methods Offset surcharges are always up for some debate. Which method to use? What is the line of influence? Is the wall flexible or rigid? Well in this segment we will…

Masonry Shear Wall Design and Analysis – ASD Force Equilibrium
Design of Masonry Shear Walls – ASD There are a few methods that we can use to design masonry shear walls, see here for another ‘simplified’ method. Here we will present a method based on force equilibrium and an adjusted bar spacing.…
Reinforced Masonry – Shear Walls ASD Simplified Method
Partially Grouted Reinforced Masonry Shear Wall Design We will cover a simplified design method for designing masonry shear walls. I don’t have a direct reference at this time however the Reinforced Masonry Engineering Handbook 6th edition and MSJC TMS402 -05/08/11 could…
Masonry – Shear Design
Masonry Shear Design For right now I am going to cover basic shear design in accordance with MSJC 2005 / 2008 (AKA TMS 402/ACI 530). I will keep updating this for strength design and include some further discussion in the near…
Seismic Design ASCE7 Part 1
ASCE 7 Seismic Design – Part 1 We are going to break down and review seismic design in regards to ASCE7-05. We are going to cover the basics and some commentary. Hopefully I will be able to elaborate sometime in…
Reinforced Masonry Walls – Partial Grout Out of Plane ASD
Reinforced Masonry Walls – Partial Grout Out of Plane ASD Most text decide to conveniently use a fully grouted wall. Well this is great but fully grouting walls can lead to unnecessary expenses and also add to seismic weight. Therefore we will look…
Masonry Walls – Partial Grout Out of Plane STR
Masonry Walls – Partial Grout Out of Plane STR It seems that most text decide to conveniently use a fully grouted wall. Well this is great but fully grouting walls can lead to unnecessary expenses and also add to seismic weight. Therefore we…
Trial Wedge Analysis
Trial Wedge Method Update: I will be updating this post or possibly creating a new post that demonstrates a simpler, clearer way to implement the trial wedge method. It should be completed by 2013/2/17. Update: I realized a couple of…

Lateral Earth Pressure II
This post is an extension of a previous post https://howtoengineer.com/retaining-wall-lateral-earth-pressure/ The spreadsheet will use the nomeclature found in NCMA’s Design Manual for Segmental Retaining Walls and Coulomb Theory. See here: Lateral Earth Pressure – Soil Basic 1 Geometry Sketch Also here is a…
