AISC Table J3.3 specifies the standard dimensions of short and long slotted holes. Is the slot length measured out to out or center to center of the radius?
We have one very old reference that shows both options. I don't have a AISC detailing manual to reference.
I am working on some venting projects for some baghouses and conveyors. We have a given vent test pressure (Pstat = 1.5psi). We need to determine the vent area and verify the enclosure strength is adequate. In reviewing the NFPA 68-2007 requirements for Pred and Pes, I have the following...
I am load rating an industrial trailer (ie not on highway) for a client. Does anyone have any references or suggested design criteria for trailer design?
I have modeled the frame in RISA and multiple vertical loading combinations to determine what loads push it to AISC 13th allowable. I think...
If you have a solid rectangular plate or bar in compression, what slenderness criteria applies in section B4 of AISC 13th?
Section B4.1 indicates that unstiffened elements are supported along only one edge parallel to the direction of the compression force. A bar in compression is not...
I am looking for design references for post tensioned concrete tank design. The application is similar to wastewater exposure. If you have any suggestions, please post them.
I am designing a structure using the British Columbia Building Code for the first time. I can't find any values for Wind Load External Pressure Coefficient, Cp in the code. Can anyone tell me where to find this information?
If the information is in another reference, could you scan the pages...
I am doing the structural design for some equipment manufactured in the US and installed in BC Canada. I am wondering if the National Building Code of Canada applies or do I need to buy the BC building code.
There is also a stack design to do. Will the Canadian codes allow use of ASME STS-1 or...
I am using the PCA notes on ACI 318-99 and am questioning if something is right. I am following example 23.4 - "Design of Precast Panel by the Alternate Design Method (14.8)". The book uses Ase (effective tension reinforcement) to calculate 'a' and Mn. I question whether this should be As...
I can't find an ICC report for Hilti HY-20 for use in hollow CMU block. Does anyone know if it is acceptable to use this anchor for a 2006 IBC structural application? If so, do you use the Hilti capacity data?
Does anyone know of any other epoxy anchors that can be used in hollow CMU block?
