  1. Waqas, The statement is asking you not to rely on temp and shrinkage steel values provided for cases where analysis shows higher amount is required. You can carry out the temperature analysis and add to that the amount of steel required due to shrinkage. You can calculate extra steel due to shrinkage based on how much strain would be caused by shrinkage or any other method if you are aware of. Thanks. Thanks.

  2. As you said, according to R7.12.1.2, first of all, reduce the modulus of rupture by half i.e. from 0.62√f'c to 0.31√f'c. Second, increase the reinforcement as required for axial tension (T=phi As fy) in addition to what required for moment.

    seismic zone FM50

    Two most commonly used standards for the design, construction, maintenance and inspection of water storage tanks, used for fire protection, are National Fire Protection Association (NFPA) standard 22 and and Factory Mutual (FM) standard 4020. While both NFPA 22 and FM 4020 provide nearly similar provisions for the design of water storage tanks used for fire protection purposes, requirements of FM 4020 are of a higher level (more stringent). By 'Seismic zone FM50', your sub-contractor would most probably be referring to the FM seismic zone with a 50-year mean recurring interval for the damaging ground motion. For more details, you may refer to the following link: http://www.pittsburgtank.com/wp-content/uploads/2015/05/FPCmag-FMvs.NFPA_.pdf Regards.

  4. W salam, In monolithic construction , T or rec beam is not a matter of choice of designer but its indicated by analysis that if depth of compression block lies below flange (flange = slab thk in beam-slab system) then the compressive force in concrete is balanced by a certain width of flange + total width of web, otherwise only web balance compressive force i.e example of rec section carrying slab load in monolithic construction. Example of rec beam sections also exists in some specific cases of construction for eg RC beams supporting metal deck system,hollow core slab panels and precast construction system. ETABS checks the eqn "a < or > ds" for maximum analyzed Mu-bott and design positive R/F accordingly.

  6. @Ahsan Kazmi right click the column and go to flexure details There you can find the design combo Check if it includes lateral loads It will also tell you the design moments for this reinforcement

    Torsion in Buildings

    1. Increase modes from 12 to have SumRx more than 90%. 2. first mode is translation in x plus some torsion. second mode is pure translation y. third mode is torsional + x-translation. it appears that you have irregularities in x direction (CM and CR are at different locations).
