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...
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...
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.

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...
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...
In the area near Edmonton Alberta:
* We are designing a non-building steel structure that could be exposed to temperatures as low as -40°C.
* It is not subject to dynamic loading (fatigue is not a design concern)
* It is not in a high seismic region.
The materials:
* A992 for the wide flange...

Has anyone had success in editing the STAAD database? I would like to add some of the new sections while removing some sections that never would be used for the heavy industrial work that our firm does (no matter what STAAD selects we would never use W6x9 in the facilities we design)
Thanks
I am attempting to write a macro that would retrieve data from text file that could be large (1500+ pages of text). The text file is the output of an engineering software package. Currently we manually gather the data to perform calculations that the software package does not handle. What I...
I'm looking for some feedback about the use of "Open STAAD". I will probably attempt to write a macro (is that the correct term?) to gather data from the STAAD output.
EXAMPLE: At a brace connection design, for the load combinations that correspond to the max & min brace loads, we would like...
Ref: AISC Seismic Provisions Section 13.3.a
I understand that one option is to design the brace connection for the full tensile capacity of the brace, but the second choice of designing for "the maximum force, indicated by analysis that can be transferred to the brace by the system" is where...
I'm looking for methods to include the seismic overturning moments (or mass) from a component (specifically a storage bin on 8 legs). The bin is on an elevated framing level of a structure that requires a response spectrum analysis.
I can enter the "dead" loads that are converted to mass at...
Thanks in advance, I would appreciate some feedback about interpreting the 1997 AISC Seismic Provisions.
The project in question is covered by IBC 2000 and is in Seismic Design Catagory D. As a result the 1997 AISC Seismic Provisions also apply. The structure is to be designed as a ordinary...
I would appreciate it if you could help a structural engineer looking for some background information.
What are the design standards that govern the design of flues and ducts that connect to boilers? Particularly for the power generation industry (primary air ducts, forced draft duct, induced...
Is anyone aware of a good reference for the analysis of pile groups that include battered piles to resist lateral loads.
A member of DFI has indicated that all that is required is to select the piles required to resist the vertical loads and then add the battered piles required to resist the...
Section J1-12 of the AISC specification requires the use of fully-tensioned high strength bolts for specific connections.
What is the basis for this requirement? It appears to have originally noted in the 6th edition of the Manual of Steel Construction and been carried through each...
