ETABS shear wall-column design

ETABS shear wall-column design

ETABS shear wall-column design

(OP)
Hi,
Does anybody know how come the results for design of a concrete shear wall with two columns at the ends of the wall is different from area of rebars for the columns in "Concrete design/check of structure"? I designed a shear wall with columns and modeled the wall with wall section and columns and for designing shear wall I used "General method" with "pier Section". Design of column itself shows I need 6% area of reinforcement and design of shear wall with "pier section" that includes shear wall and columns needs 2% area of reinforcement in columns. Thanks for your help.

RE: ETABS shear wall-column design

That issues are common in ETABS. In order to design walls, I use that tool. The wall forces are extracted from ETABS using Display->Show Tables->Copy Entire Table (to Excel) and then the design process continues on this external program, which I higly recommend.

Regards,

Gigi

RE: ETABS shear wall-column design

as stated by Johnbridge,

you need to :

1) Extract pier forces from Etabs
2) Design by sectional analysis (Can be done easily by excel spreedsheet or any column sectionnal analysis software like spColums, etc...)
