    Skipping of Loads (Pattern Loading)

    Good morning, I am wondering if ETBAS and/or SAP2000 will automatically consider Live Load Pattern Loading, please see image attached. CSI's website ( https://wiki.csiamerica.com/display/safe/Auto+pattern+live ) refers to it but for SAFE rather than ETABS or SAP2000. Currently, we have a few...

    Flexicore 1971 - Hollow Core Slabs

    Afternoon everyone, I am currently analyzing an existing structure (filing room with 8" thick precast slabs). I was fortunate enough to find load tables for Flexicore Slabs dated 1971 (8"x24" section). These hollowcore slabs more-or-less match what we found on site. Flexicore based their...

    Issues with Sframe (Periods and Base Shears)

    Good afternoon. I am working on a one story steel moment resisting frame in Ontario, Canada. I am currently modeling and analyzing the structure in Sframe. I am trying to understand why my hand calcs are not comparable with the FEA from Sframe. It's a simple structure with no irregularities...

    Index/Match function connected to the Ceiling/Floor function

    Skip, Thank you very much for your help - I did what you suggested and it worked! I assigned a (-1) value instead of (0) and it was able to extract the accurate number. I also did what you suggested with the COPY / PASTE SPECIAL - the values that was "pasted" was a "0.3" - which is what was...

    Index/Match function connected to the Ceiling/Floor function

    Skip, Actually I want excel to give me the EXACT match. Please, if you don't mind, refer to the attached image for the following explanation; "E17" = 0.3 "F17" = 0.7 The values from "F15" to "F19" are the data values in the array. "A24" = 0.38 "A23" = FLOOR(A24,0.1) = 0.3 "A25" =...

    Index/Match function connected to the Ceiling/Floor function

    Hi there! I am having an issue with the Index/Match function connected to the Ceiling/Floor function - I was wondering if you could provide some guidance. I could email you the SpreadSheet or I can try and explain it. Here is the simple explanation; (1) For these values, everything work...

    Permeable Pavement

    Good afternoon Engineers! I am currently working on the design of a flexible permeable pavement, (first time doing so). The reason to implement this material is to minimize, even eliminate, stormwater runoff. According to TxDOT, I was able to come up with most variables except the Mr...

    Excel - Equating two equations

    IDS, Thank you very much for your help. I was able to get Excel to work and the results are matching my hand calculations. I didn't mean to do anything that wasn't allowed. But just to put it out there, I am a Junior Engineering in Ontario. I just happen to be taking some classes towards my...

    Excel - Equating two equations

    IDS, thank you very much for your information. I believe I understand the logic behind the Magnel Diagrams. The shaded area between the 4 lines (equations) will give a range of possibilities for "P" and "e". I will not be able to use this method in an exam because I will not have sufficient time...

    Excel - Equating two equations

    Thank you very much for your quick reply. I would guess I'm looking for the maximum values for "P" and "e" so both equations can be validated. The left hand side of the equation must be less or equal to the right hand side. When I solved it, I assumed the left side to be equal to the right...

    Excel - Equating two equations

    Hi there! I'd like some assistance with Excel. I'm designing a prestressed I Girder. I'm trying to equate two equations to solve for two unknowns in excell. The equations are. -(P/A) + (P x e / Stop ) - (Mmin / Stop) <= Limit @ top -(P/A) - (P x e / Sbot ) + (Mmin / Sbot) <= Lmit @...

    Hydrostatic pressure on Concrete Dam

    SlideRuleEra, CVG, Jayrod12 & damsInc... I would like to thank you guys for your help. I now have a better understanding of the different approaches to take. I will download both books and utilize them when needed. My boss came in and agreed with what I had computed (following yall's input)...

    Hydrostatic pressure on Concrete Dam

    CVG Thanks for including this picture! To continue with this topic... I have a question regarding Friction Force (FF). FF = Sum of Vertical Forces * Friction Coef. Friction Coef (Concrete on Concrete OR Concrete on Bed Rock) = 0.4 ~ 0.5 For the vertical forces... Downward force from the...

    Hydrostatic pressure on Concrete Dam

    Jayrod12 Could you please explain your input...And thank you! Water creates a pressure that forms a right triangle with two equal sides... Therefore h is square (h^2) when calculating hydrostatic pressure. Since there is water overflowing the weir, the above rule does no longer apply...

    Hydrostatic pressure on Concrete Dam

    Concrete Dam Stability. I have a question regarding hydrostatic pressure. Please see picture. For purposes of the design, we will design in 1 meter intervals. Let's assume that the toe of dam is set at 100 meters while the top of the dam (weir) is set at 105 meters. Under sunny day conditions...

    One Way Concrete Slab - Metric (Canada)

    Jayrod12, Thanks, this helps a lot! Quick question, Do you happen to have the tables that allows the user to obtain "min. ration of steel" due to "Mu/(phi * b * d^2) - for different Fy and Fc' I've attached a picture (see link below) of a table that uses Fy=420 MPa and Fc'=28 MPa... But it...

    One Way Concrete Slab - Metric (Canada)

    Hi There, I wanted to know if anyone knows of a good Reinforced Concrete Design Book, a book that follows the Canadian Code and uses the metric system. I recently graduated from FSU - but just moved to Canada. I use as a reference the book I used in college "Design of Reinforced Concrete ACI...
