The base reaction moment are calculated about X=0,Y=0,Z=0 Zeros coordinate. This is not overturning moment of the building.

So if I understand correctly, we cannot edit joint coordinate using table anymore ? What a mess !

you are all aware that the load in the brace are negligible -> 0.01 seems ZERO to me !

Always find these kind of thread really scary !

I think the real question is to put compression or tension lap splice. I my opinion, Tension lap is required to be able to develop moment resistance for lateral displacement capacity (Seismic / Wind)

Very good question ! I am pretty sure that the answer to that question is linked to the ability for shear cracks to develop above shear head. On other hand, with spacing reducted and diameter increased, the calculated resistance is doubled compared to the original design. BUT : Does the...

Only Headed Reinforcements (Studs) and Stirrup reinforcement are covered by canadian CONCRETE code, thus the difference in reinforcing wording definition.

FYI It's quite common in new building in canada. Here Shearhead means "stud-rail reinforcement AROUND column" NOT "embedded steel profiles in slab joint.

moltenmetal is right... But in theory, because the engineering act is done a non-engineer, it must be supervised all along...

Just saying but wind and seismic loads are reversal loading. The accidental torsion may happen on both side of the center of mass, causing reversal of torsion component ! So, in my opinion, it is not possible to have a monolotic wall taking no shear at all in a design point of view. EDIT : In...

It is somewhat difficult to change torsional behavour of building without argument with archtects because of shear wall requirement. Anyways, dynamic analysis are required for torsional building (WTF Would you really design high rise with statis equavalent procedure, Come on !?) In my opinion...

Local buckling of thin wall segment of shear wall are covered in code by requiring minimal thickness calculated as a fraction of the net wall story height. Note that seismic clause requires thickier wall than usual shear wall.

The slenderness/buclkling check is assured with minimal moment M2 requirements. Also by calculating the amplification factor 1/(1-pf/(p_euler))­, you can see how sensitive to buckling your columns are In reinforcing concrete, you generally increase resistance by adding rebars without...

Where I live, we suppose that it's full of ice, so no wind pass through !

I fully agree here. A lot of engineer were badly applying correction factors such as edge factor using table when calculating resistance manually. The result is when using the software, resistance of often so much lower than (wrongly) expected. Note that the LRFD transition to anchorage bring...

I might be stupid... But in my opinion, Tension increase geometric rigidity and compression lower geometric rigidity ! For example, considering P-Delta / p-delta effect in analysis will increase the period of a building because all column and walls are in compression !

it's the mass that get accelerated. Not the Weight. Validate that your mass source is well defined.

Jayrod, I agree with you. I read too fast, I missed the word "tributary". I have the french version where the word "Design" is replaced by "Theorical" due to translation. If you miss the word tributary, the sentense can be intrepreted as "The theorical surface within he specified zone" My...

Are you sure Jayrod ? For me it seem it really mean the area of zone E ou W !

Canadian code recommand to use 80% reduction in bending stiffness in modelling. Slab Diaphragm act as membrane in the lateral load path.
