    Calculating L-Bend Anchor Force (Thermal Expansion)

    Alright I believe I understand the problem now, and I will check out that book to compare and contrast the difference in the cantilever methods. Judging by BigInch's post we will most likely be able to assume that there is a good deal of rotation and relaxation, and that our model will more...

    Calculating L-Bend Anchor Force (Thermal Expansion)

    Alright guys thanks for all of the input, maybe after looking at the anchor forces I'll take a look at the bending moments and shear forces between these methods also. From a practical perspective, how conservative/accurate is the cantilever equation? I feel like it gives a fairly good...

    Calculating L-Bend Anchor Force (Thermal Expansion)

    Thanks for the quick responses, here's what I've been working on. I've kept the E at 29.5x10^6 psi and used thermal expansion for carbon steel and arrived at about .008in/ft of expansion at 90dT. I used this equation for an L-bend in the 2008 ASHRAE handbook, section 45.10...

    Calculating L-Bend Anchor Force (Thermal Expansion)

    Hello, I'm having a hard time calculating some anchor forces and I wondered if anyone could help me out. An 8" schedule 40 pipe contains 140°F Heating Hot Water. The system is filled with 50°F water during the summer. Guides are located 20 ft from an elbow. The pipe has a 200 ft long straight...
