Re: modeling of 3d-frame with shearwall

[Subject Prev][Subject Next][Thread Prev][Thread Next]
     Siamak,
     
     You must prepare at least three or four nodes to identify the plate 
     element. Then assign the material properties and thickness. You also 
     have to identify it if its a membrane or a plate element. For walls, 
     it should be plate or solid. I usually assign plate.
     
     Say you have a 26' long x 12' wide and 20' high (one storey is 3m) 
     building and the West face is a shear wall.
     
     <-- 12'--->    <-----------26' ----------->      <---12'-->
     14        13    13/14        15/16       17/18  18        17
     +---------+    +++++++++++++++++++++++++++      +---------+
     +         +    +            +            +      +         +
     +         +    +            +            +      +         +
     +    B    +    +            +            +      +         +
     +8        +7   +7/8         +9/10        +11/12 +12       +11
     ----------+    +------------+------------+      +---------+
     +         +    +            +            +      +         +
     +    A    +    +            +            +      +         +
     +         +    +            +            +      +         +
     +2        +1   +1/2         +3/4         +5/6   +6        +5


        West Face           North & South Face           East Face
        (SWall)

       At the west face, the A (PLATE ELEM 1 ) Plate would be made of node 2 1  
       7 8; the B (PLATE ELEM 2) plate by 8 7 13 14. You can assign the         
       thickness of, say 10" and E=3260 KSI

        So the input would look like :

        SHELL
        NM=1
        1 E = 3300
        1  JQ = 2 1 7 8 TH = 10
        2  JQ = 8 7 13 14 TH =10

        You ca then attach your beams/girders and assign your columns.

        Hope this helps.

I want to model a 3d-frame with shearwall but ican't.can I ask you for 
helping to me.the model was prepared in SAP-()90 (ver 5.20).
     
thank you,
SIAMAK KOMAIE
