Sirs / Mam's,
Great day to all! I need your help..I need a brilliant idea with the attached file that Im dealing with right now. I have this confusion that you may have the idea of what is the correct approach
In figure A, the normal pressures of static soil pressure and water pressure were...
fellows,
I would like to ask if the propeller-like at the bottom of the equipment (attached in this thread) should be considered in designing the platform shown in the picture?
Do you have any guideline how to consider vibration in design?
Happy Holidays

Fellow Engineers,
I have this 3 types of equipments which is placed in a table top which is constructed in the midst of 1920's and 1950's. I was task to design the table top, unfortunately we do not have any vendor data (weights, speed, etc.)
Here are the equipment models found in the machine...
Fellows,
I am having a confusion with the PGA issue.
Our Geotechnical contractor submitted a report to us for a particular project where the engineer in charge stated a value of 0.52g
The peer reviewer keeps on asking in our meeting about the value we have used for Ca = 0.44Na = 0.44(1.2) =...
Fellow Engineers,
I am modelling a concrete slab using plate elements. I am looking for the moments in the slab at the center of each element. I noticed that the output gives the bending moments per unit width. What is the per unit width? Would that be the thickness of the plate element?
I...
Fellow engineers,
I have a beam on top of wall (as shown in attachment). What should be the methods of checking this beam and wall? There is a column on top of it at every 5 meters and a transverse wall also at every 5 meters. The beam is on top of wall throughout its wall length.
I was task...
Fellow Engineers,
I attached a pdf file of my staad model (a part only) of a treatment basin system (filter bed) with a continuous water flowing in it.
The basin is embedded on soil up to the beam (as shown). I would like to get an idea of the correct approach in its support condition using...
Is there a significant difference between the two?
Both are used for line loadings.
I think, it has effects in transfer of forces.
Please correct me If I'm wrong..Null lines transfer more moment than axial forces WHILE dummy lines transfer more axial forces than moment.
The question is...
Hi fellows
I would like to know what would be the difference If I will model an opening in etabs rather than just leaving it without any slab or deck?
Is there a significant effect for this matter?
Thanks
AlphaXY
How should design strips placed in safe v12? Is it enough just to cover the whole area of slab? or there is a necessary offset from the edge of the slab?
When there is an opening, Is it necessary to trim the design strips in opening area?
I have defined the response spectra in both direction
SPECX
U1 = UBC97FUNC = 9.81m/s^2
U2 = -------- = ---------
SPECY
U1 = -------- = ---------
U2 = UBC97FUNC = 9.81m/s^2
Then, Analyzed and view the story shears
I have noticed that static and dynamic values is the same for both...
Fellow Engineers,
I will be using ETABS v9.xx in my new company starting next week. I am not that familiar with this software. I have tried to study some examples and watch the learning series provided by CSI. However, I have some questions for you guys which I hope you could help me out. I...

Our computer here in our office has disabled USB access. How can I configure the settings so I may use it in times I badly need to take home my work?
Fellow Engr's,
I had my base plate analyzed as flexible using RISA BASE Version 1.02a knowing that AISC, blodgett and other methods were using rigid analysis which results to a different value compared to flexible one. If I make use of rigid analysis in RISA base it fails, but if flexible it...
Fellow Engineers,
I am using Fiberglass reinforced plastic by Arthur Kruger as my grating in my platform. I would like to ask if anyone have already used this type of grating. I am looking for its allowable deflection criteria. In our current project, We have used L/400 but it seems it is very...
Hi fellow computer masters, I'm a lil bit curious and a big question mark plays around my head. If my computer hibernates or say black out happens suddenly with any hardware (USB, Ipod, PSP, Mobile phone..etc.) connected in it, what is the best way to do, plug it out while there is no power or...
I am currently using 13th edition. however i found a large values for K compared to 9th edition of AISC. this is because the moment for each beam is considered. Does this happens to all of you when designing the steel? I am doubtful that I'm at the wrong track since my K-value is large. can...
