    Cracked stiffness values in calculation of fundamental period

    Hey wannabeSE, thanks for the response, Yes, I have seen the section 6.6.3.1 in ACI 318-14. There, the cracked values are given for elastic analysis under factored loads. But the anlaysis of modal case for fundamental period is made corresponding to the conditions of unfactored loads. I think...

    Cracked stiffness values in calculation of fundamental period

    Thanks Agent666 for your response. That s what I also thought. But there s one thing that confuses me: ACI says in R6.6.3.2.2 that "Analyses of deflections, vibrations, and building periods are needed at various service (unfactored) load levels (Grossman 1987, 1990) to determine the...

    Cracked stiffness values in calculation of fundamental period

    Hi all, I am wondering if any property modifiers (cracked stiffness values) are used when calculating the fundamental period of vibration of a building according to ACI 318/ ASCE 7? Regards, Kamil

    Ya know SAP2000, after the design p

    Ya know SAP2000, after the design process, outputs the beam reinforcemnt at three locations: left, middle and right along the beam length. I need to change some of the computed reinforcement as per the design code I am following. Anybody can help me do that? I tried to use the ovewrites, but I...
