Please read belowe: Facts about the building SDC - “C” Seismic Force Resisting System – Structural Steel System Not Specifically Detailed For Seismic Resistance => R=3, ??=3 Analysis used for building design - Equivalent Lateral Force Procedure IBC 2003 Sec. 1617.4 => ASCE 7-02 Sec. 9.5.5...

I am trying to calculate concrete breakout strength for a pier that is subjected to shear coming from a shear lag welded to the bottom of the base plate. ACI does not seem to address it and I couldn't find it at the PCI Handbook either. Can somebody tell me if there is a good reference to...

I am in seismic design category C and I am checking collectors for special load combinations per IBC 2003 sec 1605.4. Per code you are allowed to increase your allowable stresses by 1.7 when using special load combinations. My question is if this stress increase can also apply to connection...

Thank you all,

If I understand correctly my slip capacity of the bolt is not effected by external tensile force? Is that right?

Nutte, Can you tell me where I can find this equation? Thanks

The bolts under both tension and shear. I gave a hanger example to make it clear. What I am trying to calculate is the slip capacity of a bolt with subjected to tension.

Can you specify SC connection if the bolts are subjected to tension? For example hanger connection? Thanks

Thanks JAE, I appreciate your answers.

JAE, Thanks for response, Going back to thread # 726 126245 "pcoiron" who asked the question was using ASCE 7-02 which is referenced by IBC 2003 that's whu I thought you were referencing to 2003IBC. I have similar situation as he described and I am using 2003IBC. I am in a SDC "C" I have used...

In thread# 726-126245 JAE and others referenced to 2003 IBC section 1620.1.6 to explain which elements of the structure should be design for the special load combinations from section 1605.4. It is funny but I don't have this section 1620.1.6 in my IBC 2003 or any errata’s and supplements that I...

Bagman2524, On one side of the building there is a ramp that actually goes down 4 ft below basement floor.

Dear All, Is there min beam to beam girder depth ratio that allows you to assume that beam girders bottom flange is braced in case of negative bending? I have a case that my beam girders are 33in deep and the beams are only 16in. Thanks

Hi and thank you all for your tips, I am working on two storey industrial (steel framing, concrete floors)) building 50 ft high, 100ftx300ft with partial basement (75 percent of the building). 1st floor is 4 ft above grade but on one side the grade goes down almost 8 ft bellow finish floor. I...

Hey guys, I am trying to figure out what is the pullout capacity of a 1/2" dry wall attached to the stud with #8 screw. Is there any literature available? Thanks
