Some other calcs and a beautiful set of Mathcad worksheets.
"This section contains six interactive examples of member calculations which have been developed for the aluMATTER environment. These interactive exercise can be direcly accessed through the page listing.
These examples have been...
I am reading these days Ziemian's 6th Guide from Wiley. There I find a number changed for SSRC Curve 1 for the axial buckling strength of columns, I try to find the errata (not very deeply for now) and I don't find it.
Where Ziemian's 6th guide quotes .112 (see in the ellipse) the former IV and...
I have been modeling some structure just to learn and decided I didn't need the whole package of hypotheses so to keep the file clean I deleted the modal loadcase.
I used it for what I wanted, stored it, closed the program.
Then two days later I say, it would be nice to see the modes of the...
I upload here 3 files from SAP2000 v15 for comment on my first ever different excitation at supports time history. Look first the AVI to get a general appraisal of the thing.
I have set a very lightly loaded portal frame with knee braces, solved it as planar problem, and followed in general (I...
At step 11 I am not able to make appear the pinned option, once the element to be drawn is set as CABLE. I circumvent the thing by defining the cable in the model as a frame line, then pinned (the pinned option gets available this time) but otherwise the cable shows bending stiffness and upon...
Under the corner of a 1.1 m thick 1976 mat foundation washing from an irrigation ditch has caused a 10x10 m in plan, 8 m deep hole. The street level plus 4 livable levels building above is for now standing there in cantilever with some minor cracks above, quite likely with people within...
You determine phiVc per 11.11.2.1 of 11.11.2.2 and find your Vu is less than that. Let's call this phiVc1. Then, if you meet the geometrical conditions therein stated, as per 11.11.3 you are "permitted" to reinforce in shear by a method that only acknowledges a lower design shear stress, i.e., a...
In ACI 318-08 you are given data for punching check shear acting at some critical section accounting for the fraction of moment passed in shear to the column. This starts with the fraction of moment to be met in a band 1.5 h to the sides of the column, and then you estimate critical section...
Browsing some engineering site I found this new program, released yesterday. Since many are asking load questions it should be of help.
