    Beam Formulas for Multiple Point Loads.

    When I have multiple point loads or distributed loads on beam I typicall plot the shear and moment at discrete points (let's say 0.1 point) and superimpose the results for each point load. I use excel so I can make these points quite small and hence very accurate. If there is a varying load...

    Distribution of Lateral Forces of each floor

    To be more specific if I am using a 1 kip dummy load, would I apply that dummy load to a braced frame or moment frame at each floor to determine a floor specific rigidity? "God grant me the serenity, to accept the things I cannot change, the courage to change the things I can, and the wisdom...

    Distribution of Lateral Forces of each floor

    In determining the lateral distribution of seismic forces on each floor, do you recalculate the relative rigidities of each @ each floor? Thanks in advance "God grant me the serenity, to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the...

    ASCE 7 -05 WIND LOAD ON STRUCTURE WITHOUT ROOF

    I have a structure that is 20' square, about 15' high without a roof. The walls will have diagonal braces with vertical posts spaced as required. The vertical posts are anchored to concrete on the bottom and to a wale on the top. The wale will transfer the horizontal load to the diagonal braces...

    What compensation is due when sign and sealing for Engineering Firm?

    We do alot of work for contractors in the NYC area, designing temporary construction equipment; every time a worker is injured on the site, the lawyers just sue everyone. It becomes the firms problem to get a lawyer and prove that it is not culpable. "God grant me the serenity, to accept the...

    What compensation is due when sign and sealing for Engineering Firm?

    Based on your responses it is standard to have increased salary and not pay per use. Regarding the insurance, this is non-negotiable to me. Our firm and the owner/PE are sued at least 3 times per year and I want to be sure I am protected. When I was hired, I was not a PE and the pay I agreed to...

    What compensation is due when sign and sealing for Engineering Firm?

    Hi all, I am working towards getting my SE license. When my license is finalized there is a chance my employer, a PE, will ask me to sign and seal dwgs, etc... What are standard terms of payment for this? I was thinking Liability Insurance and increased pay. Regarding increased pay is it...

    Floor Joist Damage & Splices

    kootz, how would you quantify the capacity of the bolts? Should there be any concern with causing tension perpendicular to the grain caused by the bolts in the existing joist? "God grant me the serenity, to accept the things I cannot change, the courage to change the things I can, and the...

    Is the lateral force caused by a Live Load on a foundation wall treated the same a floor live load?

    In 2012 IBC Equation 16-11 there is the following load combo D + H + F + 0.75L + 0.75(Lr OR S OR R) Is the lateral force caused by a Live Load on a foundation wall treated the same a floor live load? Would it be factored by 0.75? I ask because I took a practice exam for the SE exam (by...

    AISC Steel Manual Table 4-9 what is the meaning of the dashed line?

    Looking at Table 4-9 of AISC Steel Manual 13 ed (page 4-136), what is the significance of the dashed line? It is also in the 14th edtion on page 4-137. NOT THE BOLD LINE; which is the unbraced length that exceeds KL/r < 200 "God grant me the serenity, to accept the things I cannot change...

    Two story deck with splice post only..

    Assuming that you are attached to a building on at least one side (2 is better) and the floor diaphragm is nailed well, then it should be okay. Regarding the connection of the middle post. You maybe able to find one piece to span all 3 columns OR you will need to splice it. Using 1 piece is...

    Two story deck with splice post only..

    Is this a free standing structure? Or is it attached to another structure? What do the columns bear on? Is the a pad footing? If it is freestanding, then base will likely need to support a lateral load. Assuming that there is not a footing, 3' to 4' embedment into the soil is probably not...

    Two story deck with splice post only..

    scpanchal, How do you plan managing the horizontal forces (ie. wind, seismic, nominal loads)? "God grant me the serenity, to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference" -Reinhold Niebuhr
