Good morning everyone,
I am trying to take advantage of the Interactive Data Base Editing using ETABS and whenever I change something mostly in the load patterns and try and run the model, it gives a miRunAnalysis error and also it will not let me save and if I go to define load patterns the...
Good morning Everyone, sorry to bother you
I am trying to take advantage of the Interactive Data Base Editing using ETABS and whenever i change something mostly in the load patterns and try and run the model, it gives a miRunAnalysis error and also it wont let me save and if i go to define load...
Hello guys how are you?
I am having a bit of a hard time visualizing and understanding a point regarding the design of steel moment frames for seismic loads.
I was told by my prof that beams are designed for
1.4 D
1.2 D+ 1.6L
1.2D + L +E
So here is my problem:
Lets say I have a compact I...
Hello guys hope that you are doing well.
I have a question that might seem silly.
In concrete structures as I'm reading ACI we have two methods of designing for two way slabs:
Direct Design Method and Equivalent Frame Method. Now for example for the DDM it says that this is for gravity load...
Hello everyone, while reviewing my concrete notes a question rose in my mind.
In a rectangular section, why is the reinforcement ratio As/(bd), why use the effective depth (distance from top to the longitudinal reinforcement). Why not use bh where h would be the height of the member which will...
Hello everyone, i am getting confused on a rather simple concept any explanations would be very much appreciated. I am trying to use the stiffness method to solve the following problem?
The solution is force in member 5 equals 50 kn but i cannot arrive at this number at all.
In addition if you...
Hello everyone, I have a question regarding the stability of a frame:
I may be wrong but from what I have learned to check for stability given a determinant system you must control two things:
1) Not all reactions forces are parallel or concurrent. (This frame satisfies this rule)
2) Rigid...
