why i have to repeat the vertical loads on the load case of seismic despite i have define it in seismic load definition above

Ian,First, have a look at Table 1-2 in the Technical Reference manual where the local axis system is described when the global vertical axis is Z. According to that figure, the web of an I-shaped...

Are there any reports that provide a detailed calculation of the Cs factor when using the equivelant lateral force procedure to calculate seismic forces? I have looked at the Loads and Applied Forces...

The Loads and Applied forces report is the most detailed one we have. Based on your values above, it looks like you might be in Seismic Design Category A, where the simplified method kicks in and CS is...

Plate releases does not always guarantee zero moments/stresses at element corners. There are some limitations in finite element analysis like continuity of stresses across element boundaries are not...

Thanks for the quick response Sye. I have removed the member off sets, I could see that rigid link attracting moments. I am not worried about the pile design, just the plate design. My main concern is...
View ArticleRE: tapered section on staad
STAAD calculates the stiffness by integrating over the length of the member. A total of 256 sections are used for the calculation and unfortunately this is not something that users can control.

Hi,I am modeling a series of precast planks using plates spanning between pile caps. The pile caps are modeled as beams and offset from the plates. I have used the plate release command on each node to...

If your individual spans are supposed to behave as simply supported with no moment continuity across supports, then you may consider leaving a small gap in between the adjacent elements at the support...

Offsets: I feel SACS does not create rigid link to account in analysis while offsetting. We do it to simulate actual additional forces arising from offset (eccentricity) and hence to have actual site...

Centre of Rotation:The practice in your company is reliable. We do the same. TOW is for wave load and wave arises on water level.
