    One way or two way design.

    Clif234 It's for a moment frame yes. For the details of construction I know little about, this design is only just practicing new designs. I will consider your opinions both, I think you are right maybe a waffle slab be better. Thanks

    One way or two way design.

    If I have a parking lot to design with hollow core slabs I have the dimensions in the attached file. If the panel is 12 X 12.6 m and I placed the direction of the hollow slab parallel to the 12 m span and supported at the 12.6 m span beam. should I design it as a one way or a two way ? I know...

    Special moment resisting frame system

    What differs between a special moment resisting frame and an ordinary beam column joints is that the first must have rigid joints "beam column connection". My question is how to achieve that ? Does anyone can give all the requirements to achieve it ?

    Hollow core slab - beam details

    Hello, I'm designing a parking lot with prestressed hollow core slab and dropped beams. But before I want to choose the preliminary dimensions of the beams I want to know how will the slab connects to the beam ? Like it's rebars detailing. Plus should I make the beam width larger than the...

    How to know the forces and stresses that are exerted on structural elements

    Racookpe1978 Haha I know I would get this type of answer. I'm in a university in the middle east, can't tell you which university it is. However I agree with you that I must self-study but I don't know what topics to read and study to overcome my problem And as JAE said some methods half of...

    How to know the forces and stresses that are exerted on structural elements

    Hello there, Sorry my question seems dumb, however, in college (this summer ismy last semester to graduate) They taught us how to design concrete elements like slabs, beams, columns, walls ... etc And it's very easy because always the forces, moments, etc were given. I have never encountered a...

    Wind Speed for assigning wind load.

    I have been doing it all wrong :p Wind rose values are measured 10 m above the ground. Thanks OHIOMatt

    Wind Speed for assigning wind load.

    I got what you mean. Then I must design it for more thatn 61 Km/hr. This value is from Windfinder for Ataturk airport. this value has been obtained for forecasting from 2000 to this day. This isn't a real design I'm practicing on assigning wind loads to see the behavior of the building under...

    Wind Speed for assigning wind load.

    I've read the wind rose in the city I want to design for, and I got the results of this; 61 km/hr 1 hr/year 50 km/hr 8 hr/year 38 km/hr 43 hr/year I got the average weight of these three values and I decided to design with 43 km/hr ( the average is 40.3 km/hr exactly ) Is it ok since the 61...

    Live load for fire escape

    The ASCE says it should be 4.79 KN/m2 however can this be reduced when the building is only a residential building with 2 apartments per storey ?

    Different deflections for slabs in a symmetric building in ETABS

    Hi I'm modeling a symmetric building on ETABS for practice and I noticed that the higher the slab is the larger the deflection. I'm afraid that I have column shortening which results in cumulative deflections. What can I do to check what is wrong ?
