    Change from Construction Management to Structural Engineering

    I finished my undergrad in structural engineering and jumped straight into construction management. I worked as a heavy civil contractor for about 6 years. Around year 4 I started my master's in structural engineering. Between moving across the country, dealing with long hours, and the general...

    Looking for feedback and testers for a side project (a structural loading software)

    This looks great. I think I've signed up!

    ACI 350 Flexure

    How interesting. I was not aware of this change from '01 to '06. I wonder if my firm has continued with S=1.3 based off the commentary - see C.9.2.9.1. Do you only have one load factor (i.e. soil/fluid load on a wall)?

    ACI 350 Flexure

    I'm a bit confused. What is S_d? There is a value, S, know as the environmental factor. Your moment demand is always multiplied by S=1.3. Shear is also multiplied by S=1.3 if additional shear capacity from steel, Vs, is required. You need to determine the controlling load case, U, and multiply...

    Reviewing Non-Compliant Inspections and Testings

    See if the Contractor is willing to write a letter of guarantee or warranty that the concrete will perform as specified. They'd rather get the project done and "deal" with it later. Without knowing what the pour is for, it can be tough to decide. You need to look at these issues on a case by...

    Single Angle Kick-Out Force

    To piggy back off KootK, single angles do get complex quickly. I know your objective is to use this as a beam, but even braces or compression members can become a problem. I used to have a boss who would always neglect the moment induced on an angle by axial forces. Long story short, I try to...

    Are you an engineer at all??

    No. I'm a glorified paper pusher.

    Effective Length of I-Beam

    Your braced length/effective length will be the maximum of the spacing of the members restraining the beam. If the roof structure members are spaced 1m, the effective length is 1m.

    Trench Box Design/Analysis - Reference Availability

    Interesting. Is it common for general contractors to produce their own makeshift "trench-boxes?" I realize shoring systems have to be approved by a PE and meet OSHA regulation, but how common is it to see GC's rig something of their own?

    Trench Box Design/Analysis - Reference Availability

    Hello, How are prefabricated/modular trench boxes designed? Are they analyzed the same way as braced sheet pile? Which codes govern the design process of trench boxes? If you could recommend any literature for trench box design it would be much appreciated. Thanks
