bookowski,
I've modeled it several ways. I started with a beam model. Then I worked up a quick solid model in Femap/Nastran so that I could measure the tip deflection relative to the deflection at the vertical leg. I only constrained the part of the angle that would be embedded in masonry on...
As stated in original post, I have checked stress, deflection, and toe displacement due to rotation.
I am no expert on this part, but Current energy codes apparently require a certain amount of continuous insulation in addition to the batt insulation.
My primary question was whether or not...
The architect wants the vertical leg against the sheathing - which is a condition we have been seeing at our firm a lot in the past 5 years.
I think the reason has something to do with flashing.
I am having a few issues with the loose lintels on a building project. The architect is showing 6" metal studs + 5/8" sheathing + 2" Rigid Insulation + 1 1/2" air space + brick veneer. This means that the total distance from outside face of sheathing to outside face of brick is 7 1/8". This...
I have an undergraduate degree in engineering (mechanical speciality). However, I started working for a structural engineering firm as a sophomore in college. I completed 4 of 10 graduate structural classes in order to further myself in my career and to pass the SE1. It worked; I passed; and I...
We are doing some minor modifications to this hollow corrugated concrete structural system. The corrugations are used as ducts... so at the center of each of the corrugations, there is a penetration in the supporting concrete beam.
Both vertical and horizontal minimum reinforcing requirements are listed under section 1.14 of MSJC 2005. I think that is the section you were refering to in regards to seismic design requirements. Other minimums may exist elsewhere.
As far as the reinforcing required by design, when you design...
Weird day. I was just looking at this in (Concrete Microstructure, Properties, and Materials by Mehta and Monteiro):
"There is... an ASTM standard test for the measurement of the rate of bleeding and the total bleeding capacity of a concrete mixture. According to ASTM C-232, a sample of...
My understanding is that the purpose of the sampling is to ensure that the client is getting what was ordered/specified. The actual in-place strength is dependent upon the contractor's placement and curing operations. This way, when a problem arises you have the appropriate information to...
I am advising a client who owns a multi-story office building with open parking levels on lower floors. Above the uppermost parking level there is a drop ceiling concealing the HVAC/plumbing/etc services for the office floor above. The ceiling system must have never been designed to support the...
I thought the STRM was much better than some of the Kaplan Materials I used the first time I took it. The first time, I was overwhelmed by how little time I had to look up things. I passed the second time by spending more time studying and working problem after problem. I had the 6 min...
This previous thread has some helpfull information in it... it also has some very funny quotes and comments:
Design by rule of thumb

As for shear walls, the only building layout guidelines I am aware of are in the emperical design of masonry section of the code. You can also...
I'm in an engineer-engineer relationship. He is the one that can leave work at work... and I am not. Some consulting jobs are more demanding than others. Some people are more inclined to go the extra mile each and every time they are supposed to stop walking and rest (that's me).
