thread507-478111

thread507-478111 hi there, I was wondering if any had some sample calcs to explain how a steel picture frame will work. Specifically the base beam. Have a project whereby I need to take out ground floor load bearing wall which is also providing a buttressing effect to the side walls. A picture...

No it's just a rectangular concrete tank, with horizontal tension in the walls

Hi, Designing a concrete tank where shear forces in long walls equal direct tension in short walls and vice-versa. I am designing to British Standards or Eurocode preferably. I know I must add the reinforcement required for the direct tension to the reinforcement required for horizontal moments...

Nope you answered my question thanks

Hi Jed, Found that resource on line! Thanks for that. Will the base slab have tension due to bending on the water face throught or will some develope on the soil face at mid-span?

Hi, I am trying to design the base slab of a water retaining tank. The tank is above ground and the only loading on it is from the retained height of water. The tank measures 5m by 6m by 4m deep, with a freeboard of 500mm. The moments and shears in the walls have been worked out using two way...

Hi all, I am doing some masonry panel designs (UK region)and would like to be a bit more "economical" with my design. If I can assume that the base of the panel is fixed, even with the presence of a dpc it would help reduce the amount of windposts and bed reinforcement in my walls. I believe...

Hi there, I am trying to figure out the effect of a point load on and under ground circular concrete chamber. I began by looking at hoop stresses etc and thought that the earth load will cause the chamber to go into hoop compression. But I don't think a point load will cause pure compression...

Thanks for the reply guys, The forces were based on 10 bar pressure and a 45 degrees bend, the resultants were taken from a table from a CIRIA report on thrust blocks for pipes If I removed the gap (and also there are no other forces than those due to the waterr in the pipe) what other...

Thanks, for the reply. The idea behind the stub plates was to cause a reaction between the lonitudinal force on the pipe and the strap and transfer the force to the two bolts either side. what I was thinking with regards the perpendicular force was that it would cause to pipe to want to roll...

Hi, i am trying to design a support system for a DI pipe. The system is basically a "U" shape strap over the pipe and the strap is fixed to a support base. I have been able to obtain the forces due to water moving in the pipe (along the pipe & perpendicular to it) and assumed that they act...
