    Is it possible to build classic precast pre-tensioned data centers in seismic zones ?

    What I'm loooking here is reasonable justification and example in the world of precast data centers, even though most of the collegues agrees that precast prestressed data center may built with LFRS ( with shear walls) none of them is really willing to go that way, it seems that they relly more...

    Is it possible to build classic precast pre-tensioned data centers in seismic zones ?

    The classical one is that we precast girders at the plant with pre tensioned cables, pre-cast the columns, TT Slabs at the production plant and we ship them to the site where cup foundation or continous foundation is ready beforehand, in which we errect them and comprise the column, girder +...

    Design of Retaining Wall Ribbed / Shelf Type ?

    yes that thing wories me, overturning seems to be major issue ( if I take the farthest point as moment arm for moment balancing then it comes to acceptable limits ) sliding seems minor, because one way or the other I'm planing to connect toe side with road concrete which will be at least 8~10mt...

    Design of Retaining Wall Ribbed / Shelf Type ?

    I have to design a reinforced concrete retaining wall which has aprox. 7 mt in height, on backfilled soil side I don't have much space for foundaiton protrusion which normally we use to take the balancing overturning moment from backfilled soil, active soil effect, I can create max 2mt...

    Steel Panel zone force equilibrium

    If adding some diagonal struts is enough to solve the problem IMHO surely it'll overweight the option of upsizing the column, and don't think that it'll add much to the workmanship/fabrication. The think that makes me uneasy is i couldn't understand the stress derivation of diagonal strut, co I...

    Steel Panel zone force equilibrium

    Yes you are correct. This is the crucial part, on what basis you assume/judge that it won't create the shear force. Depending on the unknowns of system, general way of solving those kind of problems is simple means of statics. Writing the equilibrium in X and Y direction, taking the moment to...

    Steel Panel zone force equilibrium

    Dear All, I'm having a difficulty with understanding, how the force equilibrium is construed in the steel panel zone in order to perform the stress checks. Regarding the book that I'm reading (Advanced analysis and design of steel frames, John Wiley & Sons, Guo-Qiang Li and Jin-Jun Li) writer...
