I am running a 25 story RC model in ETABS, and I got this message during running:
Some design loading combinations do not have results available. Design will ignore such loading combinations. Check if required load cases have been run.
I checked everything and the results are there. But I...
I have a question regarding program of work in Fidic 1987. If the Contractor failed to submit a program of work, can the Engineer ask somebody to prepare this program of work for the contractor and ask the contractor to follow it.
I am trying to use the command "Insert / OLE Object / Microsoft Excel Sheet", and after filling some cells with data, and closing the file, I can see the filled data inside Autocad drawing. BUT, if I open the sheet again through (Right Click after oject selection) "OLE/OPEN", and if I add more...
I am involved in the design of large circular wastewater basins, and I know that there should be expansion joints that devides the basin into several parts to allow for movements caused by temperature. Some engineers told me that there is no need for the expansion joints in such structures, and...
yes SomtingGuy. But I think that solving 100x100 simultaniuos equations cannot be done in few minutes as may the student do now. I do not mean that the student will become better than his tutor; but, 20 years ago, if you compare yourself with the amount of time you need to solve a big problem...
Dear SomptingGuy, I ment that you can solve 10 problems using the same time that we used to solve one problems. Therefore they can gain experience in a shorter time.
What I meant that the use of computers in teaching, in addition to the use of the internet and the email, helped to facilitate the communication between students and professors. The use of Engineering Software has made also a compulsory change in the teaching process. Students are asked to do...
I want to know the opinions of other people about the change of Engineering Education in the IT age. I think that there is a major change has been done in the way we teach and learn engineering in the last ten years. The existence of the Internet made an important role in the modification of...
Dear 1161,
Staad will not prevent you from defining springs as
FIXED BUT KFY 12000
..BUT, it is not realistic and does not represent reality.
in my view, this is wrong. it has to be
FIXED BUT MX MY KFZ 12000
in order to represent plate supported on springs.
It has to be
FIXED BUT MX MY KFZ 12000.
because if you do not allow rotation about X and Y axis then
you should have all nodes prevented from rotaions and you may have
only one level of displaced nodes.
