Hi
I have this roof truss that contains steel T sections as its top and bottom chord.
The axial force is very close to their capacity already. If I do a combined N&M check the chord will fail due to the low bending moment capacity of T section.
Now my question is do we need to consider bending...
Hi,
Code says depending on the N/fcAg the stiffness should be reduced accordingly. How do you interpret and apply this in your analysis and design?
Do you
1. Change the stiffness accordingly to the relationship between N and fcAg without checking if the section does crack or not. OR
2. Check...
Can anyone please advise on the connection and the choose of member shape of the below structure?
It is a roof with 5m high curtain wall below
I have AISC manual for curved beam. Just wondering what shape and connection would you choose for the cantilever beam?
I am checking the buckling capacity of some 200mm or 250mm wide concrete columns for a typical apartment and wondering if you would consider it is rotational restrained in this weak axis so k factor can reduced to 0.7?
For precast panel to panel with dowel bars vertically how do u check the shear capacity? Do you still use the concrete shear capacity from the wall fc or the grout one or you don’t use concrete shear capacity at all but purely reply on the dowel bar shear capacity ?
I am going to provide transfer load schedule for PT contractor and am wondering how you guys deal with the transfer gravity loads for walls? Do you simply gives line load or together with bending moment? I believe the wall will have great axial loads at ends due to bending moment.
Please see...
The client wants to change the 200mmx1000mm 'gravity' blade column to 150mm thick wall and don't mind increase the length to, say 2m, if needed. Due to the ductility requirement I still need to design these 150mm walls as columns.
So do you put two layers of reinforcement in OR,
if two layers of...
