    ETABS column unbraced length

    Does anyone know in ETABS column design how column unbraced length is calculated? Does it automatically take the slab thickness into consideration? Looks like the program does not consider the slab thickness but rather, simply take it as floor height?

    Warehouse Truck Loads?

    Thank you. That was actually what I wanted to know. I would expect the vehicle in the warehouse to be not heavy by saying 'warehouse in particular'. From the architectural plan it has the a loading bay inside the building. That said, even if the trucks unload before entering the building, I have...

    Warehouse Truck Loads?

    Sorry I didn't make it clear. The trucks are not limited to forklift only. The slab is in a slope site with part of it on ground only. And even with that slab-on-grade part it is deep fill underneath. That 3mx3m spacing is the beam to beam spacing with piers at each intersection. So it is...

    Warehouse Truck Loads?

    Thank you very much

    Warehouse Truck Loads?

    Thank you very much! Just want to confirm if I understand it correctly. So for A160, 160kN is the total for 2 wheels, meaning 80kN each wheel at 2m spacing laterally, While 360kN in M1600 is for 6 wheels, meaning 60kN per wheel with given spacing plus 6kN/m / 3.2m = 1.875kPa UDL. Correct?

    Warehouse Truck Loads?

    Thank you. I can see there are many different trucks. Does Code specify what maximum loads or trucks to be used for for warehouse in particular? Does 80kN per wheel sounds ok to you?

    Warehouse Truck Loads?

    I have a warehouse slab-on-ground that needs to be designed as suspended slab. Just wondering what loads should I use for trucks? I am designing to Australian Standards. I am not a bridge guy so have no AS5100 on hand. Currently the slab spacing is roughly 3mx3m. I believe the worst case is one...

    Curved Ramp

    But, what support the walls? Looks like it is quite a long curved 'beam'.

    Curved Ramp

    Can anyone please explain how curved ramp is analyzed and designed. Like what is the load path? Are these short walls acting like beam supporting ramp? Please find below as an example

    Irregular diaphragm

    Noted. Thank you for this helpful information.

    Irregular diaphragm

    Thank you. With wind beam placed at 4m height, the mullions will be a 4+5+1 (parapet) two back spans cantilever beam. I will expect it works at 1.2m spacing. That said, I can increase them to say 150 shs if required. Now my issue is for block A. Can curved wind beam be placed at first level as...

    Irregular diaphragm

    Thank you. I was considering 300 PFC (strong axis horizontal). Can you explain why this is not practical? (My problem with this is for block A since it is curved) Without internal restraint, the wall will span 10m long and required around 200mm mullions with closed spacing from my first guess...

    Irregular diaphragm

    Also, for the irregular steel frame shown in blue, there are voids in mezzanine level, meaning the height the frame will be 10m. The architect wants keep them within 100mm thick. I was thinking having shs columns span from footing to roof with internal restraints by wind beams at mezzanine floor...

    Irregular diaphragm

    It is in low seismic zone I have done the sketch for the latitude wind as below. Can you please explained how 'cantilever' works for longitudinal wind? (also I forgot to add that the RC wall will be precast).

    Irregular diaphragm

    Thank you. Sorry. It is steel beams + purlins on top + rob bracing.
