Dears,
ACI318 paragraph 17.1.5 says:
This chapter does not apply to [...] grouted anchors.
Grouted anchors have performed very well for many decades. They have very interesting technical advantages. Is there a way to design them according to the standard?
Thanks,
Daniel
Hello,
I installed version 24.1 of the software. It doesn't let me import dxf files correctly. It also doesn't matter the csi sample file (as attachment). Do you have the same problem? How do you advise to solve it? Is it possible to downgrade the software? Unfortunately I no longer have the...
Hi,
Only the three fabrication methods showed in the document below are permitted?
http://www.cim.mcgill.ca/~paul/HollowStruct.pdf
A fabricator want to fabricate a rectangular HSS by welding two plates (rolled in L section) in two corners of final HSS.
Thanks,
Daniel
Hi,
I am looking for a book that is a complete guide for the steel connections design. I want to implement a spreadsheet for each type of connection, and I need a complete text where to find all the verification for each connection. Do you have references of books that can help me in this...
Dear,
Good Morning. I would like to share with you some reflections regarding the calculation of truss box conformed by single angles. I am using the AISC 360-16 standard. As I understand it, I have two ways to check angles.
1) Neglecting the eccentricity of the axial load in the angles (axial...
Hello,
What standard defines the load test for a safety line protection system?
I want to know if I can certify a safety line using a non-destructive load test.
Thanks,
Daniel
Dears,
I'm implementing a calculation program to design castellated beams according to Design Guide 31.
In chapter 3 the following limit states are listed:
1. compactness and local buckling
2. overall beam flexural strength
3. Vierendeel bending of tees
4. web post buckling
5. Axial tension /...
Dear,
I am designing a powdered coal silo, which is subject to explosions. I would like to know if you design these silos taking into account that the relief valve limits the pressures, or if you calculate the silo based on the maximum pressures.
What explosion pressures do you use? I found...
Goodnight,
I am implementing the verification by axial and flexion of tee sections, to use the DG31 (cellular beams). I have the following question: does the AISC not consider the flexion in minor axis of the tee sections? How can you calculate the resistant moment My? Can you assimilate the...
Dears,
There are structural engineers who usually apply a criterion of frequencies for industrial steel structures (not subject to vibrations of equipment). Some use f> = 2Hz, others f> = 3.0Hz, etc.
What is your opinion? Do you use that criteria? If yes, what frequency do you use to ensure...
Dears,
I am designing a steel industrial warehouse with span of 40 m. The steel structure is made of truss beams and columns supported on concrete columns 5 m high.
I understand what is the seismic behavior, but I can not find the design method in ASCE 7-16, especially with respect to the...
