Dear All Does anyone has experience or suggestion on connection of hollow prestressed concrete spun piles subject to tension with their pile caps. Our large spanning warehouse with strong wind resulting in net uplift force in these PHC piles say 20-30 kips per pile.Problem to us is...

Thanks ALL. In my case I have series of T-shaped column 21 feet high with very light loads say 1 kips on top with small eccentric. With slenderness kept within 200 it comes up with too heavy section for me comparing to others such as street lighting. Burtoni your value based on experience...

Could anyone give me the light to the background of limitation of 200 for col. slenderness. could we design column such as T-shaped frame with small load on top of its with slender over 200.? Does anyone know sources or information in predicting capacity such kind of this slender column. Thanks

Thank Ron, Rjeffery,Rapt. These are more informarion; - This warehouse is just single story, slab that I mentioned is slab at grade rest on piling support. - This warehouse was fired more than 4 hrs. Somebody said that all night long. The Steel roof truss was totally...

Could anyone simply explain meaning and purpose of this test Thanks for help

Does anyone has suggestions and checkpoints for concrete slab and rebar under fire. I have participate in assesment of this slab for warehouse which damaged by fire( more than 4 hrs). This warehouse use for chemical raw material stocking. After fire the superstructure was demolished, but we...

KRSServices, nealt Thank you for your helpful hints. We checked the pond by check depth of water in various points along the pond,as nealt said it is diificult to check exact volume of pond. The problem is the client may not accept this pond as they quote that have to pay for...

Dlew In case of PC. wires , do you have an idea how to calculate development length to tension force.

KRSServices This pond is currently leaking, what I have no idea is Is this leaking quantity is normal acceptable for such kind of this linning. Also, I understand that there shall be some evaporation. how can I calculate this figure. Thanks

I have problem with leakage in Raw water pond lining with 1mm.HDPE SHEETwith welding joint type. My pond was 90 m. by 45 m.water level is 3.5 m. The water level is lower 1.2 mm./hour which is 2.88 cm/day. My point is we cannt find the criteria that this is accepatble for such kind of this...

Steve1 Thanks for your kindness , my add :lsurakiat@hotmail.com

Could anyone has idea about using prestress wires in PC. pile to transfer tension in pier. My colleague in office say that in case of piles subjected to tension due to wind such as in PEB building were penetrated too short and dowel have to cut out to reach design pile top level, we can...

steve1 I'm looking for anchor forces come from thermal operation, I've some estimating formula for preliminary design( as I stated before not detail design) such as in case of equal-length-tanget-U-loop ; Px = Kx . C . I / U2 (kg) Sb = Kb . C . D / U (kg/cm2) I'd thank...

Could anyone suggest what is the minimum thickness of pipes that can welded in case of light structure?

hyper! What am I understanding you should not go further with P-D analysis without checking approx. means proposed by ACI. such as Q-stability index- first You should prelim. anlysis your frame with first order by reducing stiffness of columns and beams. ( 0.7 and 0.35 ). and...

pipesnpumps, steve1 Lot of thanks for your help. pipesnpumps---could you tell me more detail of ITT-grinnel manual, how can i get this informatiion. I'm not familiar with any pipe textbooks. What i want is to roughly estimate this anchor forces to my piperacks for preliminary...

I've been modeling 3-d FEM by using shell element for slab and connected to beam, the result of shear and bending even load tranfer to beam( by results of shear )is quite difference from conventional method from ACI. They give me with less moment in beam compare to ACI method. Could anyone...

Could anyone advise me the way to desin or get information to calculate anchor forces from pipelines to support eg. piperack. Thanks
