Hey, I know it's a silly thing to ask, but I kind of forgot such terms. Is the moment about the local x-axis (as shown in the figure), transversal or longitudinal moment?
Hello mates, so here's the issue. I have 2 towers connected together at a certain level with a bridge. I've done my analysis, and hinged connectivity between bridge and the floor slab was structurally the best.
My question: does the detailing presented in the attached image, by not providing...
Hey there, attached is an image(preliminary one of course) of a post tensioned slab. Does it seem to have anything wrong concerning cable distribution (for example spacing between adjacent cables, etc...)?
p.s. cables in horizontal direction: 4 strands per cable / cables in vertical...
Hey, by what value shall we embed the beam rebars into exterior columns, so that pin condition is achieved?
I've previously heard that it's (0.1-->0.15 * effective depth), is this true?
Hi every one
i am doing a research about several techniques used to improve the bearing capacity of the soil
i found a lot of techniques used but what i didn't found the effect of using for example stone column on the bearing capacity of soil
can any body send me please a guide how we use this...
Hey there, are there any specific websites that list global and local costs of such material? The site I used to rely on seems to have shut down. Thanks in advance.

Hello everyone, here's my issue... I've modeled a 3D Frame, and when I press the calculation button, the program terminates; but one among 15 times it gave me: "Incorrect Data, Error Nr 5000". What might be the issue here?
Hey everyone, I need some help in understanding fatigue in concrete rigid connections due to high moment, and due to cyclic wind & EQ forces. Any links, pdf files, etc provided concerning this matter would be of much help.
Please check the attached image. I am particularly referring to fatigue...
Hey, I'm having a project where I have two 130m-towers linked by five (7m*7m) bridges. I've excluded the cases of Rigid-Roller & Hinge-Roller after making models and analyzing them, but I'm having a difficulty in determining the best structural connectivity between Rigid-Rigid, Rigid-Hinge, &...
Hey, I wanna ask at what level Shall EQ be inputted in ETABS? Starting from the base or starting from the ground floor? Cuz I've been told from the GF, and this frankly isn't convincing... Any help?
I have posted this on the ETABS forum but it seems it didn't get any attention. The drift in my model accounting for combination "EQUAKEX" is exceeding 0.02, which is not allowed by UBC 97.
The natural period in my building is about 5.89 s which is too much in my belief. I've checked the...
That's a thing I shall try. If I may ask another question: the drift in my model accounting for combination "EQUAKEX" is exceeding 0.02, which is not allowed by UBC 97.
The natural period in my building is about 5.89 s which is too much in my belief. I've checked the elasticity of concrete...
Hey,
I have a project where I have to model two 130m towers connected by 7m bridges at 5 levels. I was asked to consider as a senario the bridges pinned from one side and a roller from the other , and the only way I could think of is by introducing link elements.
Now here's the question: is it...
i am doing a model in etabs for a tower of 24 story at top roof their is a helipad, i am wondering about the design criteria like load value i should take it , and the impact of the helicopter when landing.
i searched a lot for a manual for structural design for helipad i didn't found...
