Thanks for the reply. I found the problem and feel like a fool. There was a tiny white line segment off to the left that I couldn't see because the artboard is white. Thats what was screwing everything up! And the reason it was a problem on multiple figures is because I simply copied then...

Extra "white space" when inserting EPS figures in Word 2010 I am writing a report on my research, and I need to insert Matlab plots and various other images using EPS format for maximum image quality. My plots from Matlab must first be exported to Illustrator for annotation before inserting...

Hello, I'm trying to use mathcad to do Rayleigh-Ritz approximation of the critical elastic buckling load of a joists top chord. The joists support a standing seam roof which acts to stabilize the top chord from out of plain buckling. In order to approximate the buckled shape, I chose to use...

Why would you post this in my Simscape thread?

134 views and no replies :/ I guess no structural engineers use this software. So far in my experience, it has been quite the PITA to built models in.

hmm, does anyone know why there's a difference between the book and simscape then?

I am trying to create a model in SimMechanics of a simple damped frame. I am very new to this software and structural dynamics as well. I have a copy of "Dynamics of Structures" 3ed by Chopra. In the textbook, the author uses the standard geometric and material properties that I am familiar...

Hello, I am assisting my professor by investigating the usefulness of Simscape in structural engineering. I have just recently obtained a copy of Matlab, and I am totally unfamiliar with the entire program as a whole. I was wondering if anyone knew of any good reading materials or tutorials...

Tried doing it a different way and got it to work

Ha, I meant E=5000ksi in the problem statement; my apologies.

Homework Statement Homework Equations [k]{delta}=F The Attempt at a Solution I found I(x) and confirmed it manually. Basically, I think my confusion comes when finding delta. Delta is a 2X1 array of -d and -theta, respectively. I used equations for deflection and rotation for a...

Mods, I wasn't sure where to put this, so please move it if its not in the correct section. Thank you. I am in a computer structural analysis class that utilizes MathCAD as the means for all computations throughout the semester. I've never used it before, so I am having some issues. I have...

I was asked by the CE to do a fatigue calc for a speaker pole going up in key west. I am using AASHTO standard spec for structural supports for highway signs, luminaires, and traffic signals. he said to assume a Vc of 45mph, an importance factor of 1.0 (from category I-lights in the...

anyone?

Does anyone know the phi factors for overturning, sliding, and soil bearing in a small reinforced footing? If you could site the precise source too, that'd be great. I don't have access to many up to date specs and codes :/
