ok, I have no solution to the problem.........

shouldn't the stiffness be 200 000 MPa? That is what I assumed.

I am assuming the hinge is frictionless. I mean, should I do some centripital force calculation?

GregLocock and rb1957. I will try to restrain at single point, if not feasible an entire edge. Greglock, what should be the expected stiffness of a steel block of lets say 3" x 6" Thanks,

I have a heavy duty door, lets say 40kN. I have to design a stopper to qualify the door for design basis earthquake. Now, lets say I use the floor response spectrum, and it is acceleration of 1 g. I need to find the design load for the stopper. Now, I assume a force of 40kN (40/g*1g)...

For eccentrically braced frame, with link beam, what would e usually be? As well, it says in the code the laterally support the top and bottom flange of the link beam at the end. How to support the bottom flange laterally? Connect an angle to the jbottom/top of the closest beams/joist? How...

so far face is the face against the soil and near face is the face not against soil? Is that correct? How about retaining wall with soil on both sides?

Can an eccentric bracing and a x bracing been used in the same building? But how would RdRo be, which Seismic force should be used? As well, S16-01, what does 27.7.9.2 and 27.7.11.1 mean? What exactly does the code mean?

In addition, knee brace is essentially a special eccentric brace. So knee braces are designed as eccentric braces. Am I correct?

There is usually Inside Vertical Face and Outside Vertical Face for a retaining wall and a foundation wall. Which face is the "inside face" and which face is the "outside face? Thanks.

For eccentrically braced frame, with link beam, what would e usually be? As well, it says in the code the laterally support the top and bottom flange of the link beam at the end. How to support the bottom flange laterally? Connect an angle to the jbottom/top of the closest beams/joist? How...

rowingengineer's motto: "Arguing with an engineer is like wrestling with a pig in mud. After a while you realize that they like it."He is calling all engineers pigs. muhahaha, good job Rowing, keep on rowing. Actually why pig, why not monkey or gorilla or hyena? Anyways keep up the great...

Which section in NBCC states this? Do you recall?

NBCC says something about 50% Live load to be applied. Do you know which section? Thanks.

Are you an engineer? How can you not know gerber beam?

I am a little confused about the different load combinations to check for a gerber system. Is the load combination LL+DL whole length, DL whole length +1/2LL on cantilever and DL whole length +1/2LL middle? Why 1/2LL? Obviously LL+DL whole length would govern. My other question is how to...

I am mounting multiple panels onto unistruts, all panels have different sizes. How are they usually mounted? Bolted at any spots or they have hooks at the edges?

Everything makes sense until, "Use the principal axes to check the point at which the stress reaches the yield stress." How to use the axes of rotation to check the point of yielding stress. Even if I have the point where it will yields, what purpose does it serve? How am I getting a...
