• von mis stress, principal stress, and yield stress

    Hi, I try to design a bin using the plate element. When I check the stress summary, Staadpro provided the max von mis stress (top and bottom) and max principal stress (top and bottom). My questions are: 1) The yield stress Fy of the material I used…
  • OpenStaad GetResultantForceAlongLineForPlateList function to returns forces and moments along the cut line for a particular load case in plates

    I have 3 issues with trying to use the GetResultantForceAlongLineForPlateList function that I suppose are probably the cause I can't retrieve yet the resultant forces along a line of cut plates thus any example, supplementary data or help would be truly…
  • Underground concrete chamber

    Hi all, I am designing a underground concrete chamber which has pipe penetrations. I have modelled it using plate elements as shown below and used elastic mat with relevant subgrade modulus for support. The local Z is on the exterior face of the walls…
  • Plate Stress Interpretation using Von Mise and/or with Master Slave Command

    Hi, Can anyone help me interpret the result of analysis where I modelled group of plates to resist a certain Pipe Load. Loads are acted on Node 340 then Slaved to the point where the bolt of the U-type pipe support will be located. My question is…
  • Plate moment Mx and My (Negative and positive)

    Hello I am new to Staadpro and I modeled a slab (1.5m) using plate mesh (0.5m x 0.5m). How can I get Maximum and Minimum Moment (MX and My) for design? Should I take Max top stress (kN/m2) and multiply by (0.5m x 0.5m x 1.5m)? One of my senior Engr…
  • PLATE STRESS AT TOP AND BOTTOM SIDE

    Good morning, I have to make question about STAAD Pro output plate stress ; in particular, I'm going to make a post processor excel file aimed to design concrete reinforcement of a slab according to ACI Code. Is It possible, for each shell, to obtain…
  • Mat Foundation using Plates

    Hi, I created a STAAD file using Plates in STAAD and created an excel file for design. I would really appreciate if someone can check my procedure If this correct design. Especially using the stress in plates and design it in one-way and two-way…
  • RE: Spectrum Load Case, Base pressure

    Owing to the very nature of response spectrum analysis, the response quantities like displacements, support reactions, base pressure etc. are all positive. Since the signs are lost, it is not possible to determine whether a node is moving up or down by…
  • RE: Plate stresses in STAAD.Pro

    The Principal stress lists the maximum principal stress (SMAX) and minimum principal stress (SMIN) and maximum in-plane shear stress. Detailed explanation on these stresses are provided in section 1.6.1 of the Technical Reference. Also derivation of these…
  • RE: plate stresses

    1) Principal stresses: SMAX and SMIN - see example 18 in the example manual for their derivation. It leads to four stresses called SMAX_top, SMIN_top, SMAX_bottom, SMIN_bottom. Max Top - Larger of the values between SMAX_top and SMIN_top Min Top…
