Here is a conundrum. In doing an analysis on a reinforced concrete frame type (multi-column) pier, we are using AAASHTO LRFD code and looking at the strength and service load cases. In so doing, we are finding the service load case is producing larger demand as compared to the strength load...
All good ideas folks. Thank you.
I've attached a quick sketch so you all understand the detail (I've not shown the connection, though).
If you have other good ideas, please let me know, along with good ideas for blocking.
Thank you...

This is close to the right idea, but the 2x8 cantilever beam needs to pass completely under the 13.5" header, and I am not able to find a hanger that has enough depth to support the 2x8 and wrap up and over the header. If I get a chance, later today I will post a sketch for further...
For aesthetic purposes, the architect is proposing a cantilever timber beam that is placed under the header so that the bottom of the cantilever member will line up with the ceiling inside so that it looks like the ceiling extends indoors to the outdoors (the header spans a large window opening...
I am rating a bridge from 1917 plans. In the stress table it shows net area, gross area and "bal". Do any of you know what "bal" stands for in the stress table?
Thank you
I am looking at a 1917 RR Bridge Stress sheet, and it shows the net section properties, gross section properties and "bal". Do any of you know what "bal" stands for in the stress table? I have never seen this listed before on other old plans for bridges I have rated.
Thank you.
Thank you for your input. I will review them and see what I can come up with, and if I do pursue something different, I will post what I am doing.
Thank you
All:
I have been in this business for almost 30 years (designing and managing structural projects)and have enjoyed it, but am curious to explore alternate careers where I can use my structural engineering skills. Do any of you know of other structural engineers that changed careers that...
In years past, The James F. Lincoln Arc Welding Foundation published a book entitled Prestressed Welded Steel Structures. There is some good information in it and at least one example of a bridge designed by TY Lin that was constructed in Idaho.
The book was published in 1988, and you may...
Another old movie that had an engineer as the star, was No Highway in the Sky. The lead character was Jimmy Stewart. He plays an eccentric engineer who theorizes that Britain's new Reindeer airplanes will disintegrate after 1440 hours in the air. Finding himself aboard one of the planes as it...
I've had an HP41CX for 20 years, and it is still working perfectly. I am hoping it can last until retirement for me, but if it doesn't, I have one more I bought that is in great used condition.
I have had an older HP repaired by an individual, and he did a good job. He has repaired other...
