Hello, everyone!
I’m currently working on a cable-stayed bridge project and diving into the AASHTO construction specifications to identify the minimum requirements for materials used in concrete bridge decks. Specifically, we are exploring the use of a sprayable waterproofing material to apply...
Hi everyone,
I have reading AASHTO to determine the procedure and requirements for load testing (test on completion, also know as the acceptance test) prior to giving use to the public service. However AASHTO is not clear on the requirements for this acceptance test. My last project, the...
IS there a specific codes from AASHTO or ASTM that would suggest the diameter of Tie Wire that's a minimum requirement for in-situ bridge girders. I have looked at ANSI/ASTM A82, they just referenced the cold drawn steel wire that could be used based on its tensile strength, but I am dealing...
How can I simulate sloshing using the smooth particle hydrodynamic method in ABAQUS? Can someone ref me to a sample procedure utlizing time history data. The problem I’m having is how do I input the time history data and specify the boundary conditions to accurately simulate sloshing.
hello everyone,
I have a stiffened extended shear plate to a column web connection. The beam is subjected to both shear and axial forces. The beam is also in tension. With respect to axial force, how do I calculate the axial force that would be distributed to the top and bottom flange weld...

How to calculate the Snet, the net elastic section modulus of the plate. See attachment.https://files.engineering.com/getfile.aspx?folder=45f2d3fd-ccf7-4fca-8537-0b4d8b56c24d&file=34994A83-05CC-45AA-8A1D-8B3087D5D4BB.jpeg
A lot of persons don’t know the math formula to calculate Znet, the net plactic section modulus. AISC design manual table 15-3, the znet values are given there based on the bolt size, plate thickness. Etc, see code for more info.
Let’s say for example, we have a shear plate, and we want to...
Hello everyone,
What’s the allowable period to keep formwork in place for a rc wall before adding fill and compacting. In this instance my wall is 4ft in height and 6 inches thick.
Thank you

Can someone refer me to a cad detail or any detail as it is with respect to the connection between the masonry units and seismic steel frame? Is there any spec for the gap and bond epoxy used?
thank you
Hello Everyone,
Firstly, is this correct, when bolt configuration of a base late is inside the flanges of the column, it's considered to be pinned, and if the bolts are placed outside of column flanges, it's considered to be a fixed connection?
Secondly, in general, I noticed that pinned base...
Hello Everyone,
I attach a sample calculation as per asce7 as it pertains to redundancy factors and load combinations. My question is, The Force Qe, did I interpret the code correctly by using the seismic story force for that level in both longitudinal and transverse directions?
Thank...
Hello Everyone,
I'm using aisc design manual, table 3-19 to do a composite beam design. My question is, how do you calculate the PNA of a composite section?
Thank you.
Hello Everyone,
My question is when calculating drift for steel portal frame steel structure, does the Ridge/Apex level need to be checked also or is it only at Levels with diaphragms?
Thank you
Hello everyone,
From asce7-05 guidelines and aisc341-05, Is this the correct interpretation as it regards to redundancy and overstrength factors being incorporated into load combinations.
Regarding the use of the redundancy factor:
When it is determined that ρ = 1.3 in a given direction, the...
