    Pole footing embedment in soil

    Hi All, I'm designing a small garage addition with concrete retaining walls supported by piles. I'm using Enercalc V6 to calculate the pole embedment depth considering wall active soil pressure and soil passive resistance per soil report. The soil report clearly stated that the piles may be...

    if-then program hangs

    Thank you Electricpete & CajunCenturion. This solves my problem. Actually, I gonna tweak this a little bit and add this to my spreadsheet about lateral loads. Yeah, this conditions can be done without vba but what I'm really planning to do is to lock or unlock cells with a value of a cell...

    Shearwall With Force Transfer Around Opening

    I have been reading old treads regarding Force Transfer Around Openings of Wood Shearwalls, but it seems like there were varied interpretations of where the holdowns will be located, whether at the ends every shearwall segments or at the ends overall wall width. I just wonder if there are...

    MOMENT FRAME 2007 CALIFORNIA BUILDING CODE

    Thanks Whyun... It looks like if we will not check the redundancy per ASCE 7 section 12.3.4.2 where (p) can be taken as 1.0, then we need to multiply our horizontal seismic forces by 1.5 (from 20% flexible diaphragm assumption & 1.3 redundancy factor) to get the wood shearwall sheathing/nailing...

    MOMENT FRAME 2007 CALIFORNIA BUILDING CODE

    Hi Again.. I have additional questions regarding the new code. LADBS Interim Bulletin, "Method for distribution of lateral forces in wood frame buildings assuming flexible diaphragm", it says that diaphragm can be assumed flexible by complying some listed conditions, one of which is the...

    Simpson Strap on Top Plate Connection

    UcfSe & RARSWC Thanks for your reply... I just have some additional clarification on RARSWC explanation. Your example is assuming that the joint on double top plates are lined up. How about if you have to offset the splice using strap at every 4 ft too, would it be theoritically...

    cantilevered diaphragm deflection

    Hi... I just want to verify from u guys if what equations are u using to calculate a cantilevered diaphragm deflection. Are u using the equation 23-1 of section 2305.2.2,ibc 2003 or equation 23-2,ibc 2003 of section 2305.3.2 is more appropriate? or are u using other equations.. thanks
