you want to use database tables def add_gridlines_for_system(SapModel,grid_sys,gridlines, ord_type='coord'): """ grid_sys='G1'; gridlines=[['01',[-19660,20910],[-22520,43740]], ['02',[-8614,24430],[-12540,45580]]...

I think any structure which are designed for earthquakes, which includes all buildings that I can think of, L-class reo cannot be used. That pretty much limits you to the secondary elements like retaining walls or facade panels. Mesh still has it's place though. It's wonderful for crack control...

The location of a few items are a bit confusing. High strength concretes seem to have a higher requirement for confinement reinforcement & ties due to concrete brittleness, which I think would be better placed in the relative locations of section 10 & 11 instead of being placed in section 14.

I have had more luck with gridlines using the database tables

my preference is the rebox. Easy to install, good anchorage with the u-bars. This is for lightly loaded connections with a couple of metres trib width to support. When the loads are getting bigger I go the ancon or peikko inserts. Have done localized blockouts when the loads are large and the...

The boundary setbacks are already in place for new build. Building renovations get the benifit of remaing on the property boundary. It comes up in Sydney a bit, developers choose to refurbish over rebuild to get that extra sellable floor area. My gripe is the separation at building movement joints.

I'm going to make a comments and suggest building separation of adjacent buildings to be greater than the sum of the maximum displacement of both adjacent buildings. Separation of two adjacent floor diaphragms set apart by a building movement joint where shear transfer across the joint is...

It was using python, a comtypes error, I believe the message was an index error out of range using comtypes safearray. I uninstalled and went back to using Etabs v20. I won't have time this year but I'll dig a little deeper into it over the holiday break.

it's a difficult website to navigate and the make suggestions. Has anyone made comment on the pounding / building separation section?

has anyone else getting errors when using the cFrameObj function when using the API with python in the V21 release?

Thanks Trenno, I'll download and give it a read. It's good to see that the scaling up to 70% is being re-introduced thread744-501807

I would interrogate the modes which have very little mass participation like modes 5 and 6. If you are performing this analysis as part of Earthquake design you are interested in the UX, UY and RZ. It appears you might have "Include Vertical Mass" selected under mass source. This will generate...

I think simplified wall method should go. I stopped using that around 2016. I think every vertical element should be designed using and interaction diagram and the slenderness rules of Section 10. My definition of a column is that any one of the following 4 is satisfied than must be designed as...

I saw some of the demo photos this morning. That's some solid brickwork. Certainly don't build brickwork like that these days

I've never seen a wrecking ball used in Australia, are they legal?

A building commission was set up by the NSW government for residential buildings after Opal tower, and by in large I think it has done a good job. I am expecting to see something similar here with historic buildings. I know it was a roaring fire but the fire started at 4pm local time and the...

As soon as we get a decent wind blowing in Sydney those walls are coming down. Structural Engineers are going to cop it over this one. Same with those aluminium facade panels which kept catching on fire, and the whole debacle with Opal tower. Every historic building in Sydney (over 50 years), is...

I had some questions about ks a few years back in this thread. But it was similar to the previous version of the code where shear reinforcement in a slab was required above phi*Vuc and shear reinforcement in a beam was required above phi*0.5*Vuc (I think where the requirements). thread744-489155

If performing a dynamic analysis, don't forget to take into account the vertical actions from earthquake thread744-490596

you need to get all the load combinations, then set them to True for analysis results. comboOut=SapModel.RespCombo.GetNameList(); for i in range(len(comboCaseLst)): caseForOut=comboCaseLst[i]; SapModel.Results.Setup.SetComboSelectedForOutput(caseForOut,True)...
