Thank You, I appreciate the assistance.

Thanks for the quick reply. Here's how the reference appears in the AISC-LRFD 2nd Ed. The Dec 2008 edition of Modern Steel Construction indicates the provisions were first published in 1992.

I am working on a project where I must evaluate the effects of complying with the current codes relative to an older code (ASCE 7-95). One item of comparison relates to SCBF requirements. ASCE 7-95 refers to the 1992 AISC Seismic Provisions. I cannot find a version of the '92 provisions...

I am interested in information regarding structural design in Austria. Are the Eurocodes the governing codes? Are there local supplements that amend or edit Eurocodes? Are there restrictions regarding who may provide engineering services? What agencies might be able to address these points? What...

If you are using IBC, it depends on your foundation system. Carefully review Chapter 18 of IBC for the sections relevant to the system you are using. Also consider the loads that will be imposed should the SCBF plastic mechanism is developed (yielding of the braces).

I would contend that these circumstance are not limited to Illinois. Hawaii also has similar regulations regarding an SE (usually referred to as a Practice Act). Washington, California, Oregon, Utah, and Nevada have limited versions of a Practice Act (there are restrictions on what services a...

Regarding the approximate factors used to calculate moments and shear listed in ACI 318 Section 8.3.3 (2005 Ed. is in effect for this question) Two factors are listed for positive moment of an end span. One for "Discontinuous end unrestrained" and another for "Discontinuous end integral with...

SCBF connections have several limit states that must be considered. Section 7.1 indicates that the controlling limit state must be ductile. That is, the limit state with the lowest value must be ductile failure mode such as yielding of the plate or "plowing" of the bolts rather than a...

If it is part of a means of egress, a guard at 42" is required in addition to the handrail. (Refer to IBC 2006 Sec 1013).

Thanks southard & rbalex, your quote from FL & CA provide some of the most clear interpretations for responsible charge.

Thank you for the replies. Your interpretations are in line with mine. Specific examples are sought so that independent verification can be applied to similar (but not as clear cut) situations where there are differences of opinion between staff at different levels in the organization. The...

The term "responsible charge" is used by many states to establish who may seal or stamp engineering documents. The definitions offered for the term are usually open a degree of interpretation since it would be difficult to write a rule or regulation for each conceivable situation. Our office...

The firm I work for is looking into the potential of designing an industrial structure that would be built in Gujarat India. It would be structural steel construction and the site would fall into Indian Seismic Zone V per the National Building Code of India. During conversations with...

I highly recommend Blodgett's "Design of Welded Structures". Although it was written several years ago and refers to the AISC code its methods are still applicable no matter what your jurisdiction. It can be purchased directly from the publisher at a very reasonable cost...

Ditto to ajh1. The W27 is very likely to have more than adequate strength BUT the torsional deflection needed to develop that strength could produce unacceptable results. All of the details suggested appear to address the connection of the HSS to the beam flange, but I would suggest that...

Thanks to all for the quick feedback. We have chosen Option 1. One of the primary reasons for making the selection is that it directly transfers load from the slab to the CMU, rather than from the slab to an angle and bolts to the CMU. Further, the architect preferred it since it is less...

Response to masquared48: It is a combined bearing/shear wall (resists both shear and gravity). The slab/wall interface described is intended to transfer both gravity and shear loads from the second floor to the wall. The wall carries both gravity and shear from the roof over the second floor...

There is a discussion in our office regarding the best detail to use at the junction of an elevated slab with a CMU wall that would continue from below to levels above. The elevated slab will be a joist supported 4" slab on 1.5" form deck. The wall is an 8" CMU shear and bearing wall. One...

Our firm is the engineer of record on a project in a remote western states area. The project will involve several mass concrete placements of over 1,000 CY each. The local suppliers have concerns about meeting the delivery requirements (contract limits duration of placement to 8 hours) from...

I am preparing a proposal to design foundations for large industrial upgrades (column loads from 10k to 300k, 150k uplift). Large industrial fans (3000 hp) and a tall chimney are also part of the project. The geotechnical report provided by the owner indicates that the soil consists three...
