Hi all, For lap length determination, ACI says, we need to use the smaller diameter bar in calculations. Normally by logic we have to use larger diameter bar. Could anybody here explain the the reason behind?

I once used 1 1/2" tube for connection design. And 3 1/2" tube as a column like SperlingPE did.

I need to check an existing 8" thick two-way concrete slab for an eccentric distributed load of mechenical equipment of 60 PSF. The dead load of the slab is 100 PSF in addition to permanant dead load of 40 PSF. The total load on the panel is 200 Psf. It is a 24'x15' typical interior salb...

Hi, The conventional way of analysis of trusses is by considering the support conditions as simply supported. Alternatively you have to detail your supports to simulate the simply supported behaviour. hope this helps You may mail me to pvsreedhar@postmark.net for more info sree

Yes, there will be partial fixity at panel points because of new welding. Also since the supports are firmly connected to the existing structure it may at more like fixed support. Considering the fact that it is quite old building it would be wise to be conservative in the analysis and design...

haynewp, For smaller openings (<8 ft) we use trough shaped reinforced grouted bond beams as lintels. You can see these kind of lintels in most of the CMU load bearing constructions in US.

You might specify what kind of lan you have? Assuming you have windows NT or 2000 notwork, You will typically have a server and several workstations. You need to know administrator password first to create and control other users. After you log into the server as administrator, you might go to...

yeah... I agree with DaveAtkins, but the friction coefficient is 1.0 for roughend concrete.

Rufus182, I have not heard about the static coefficient of friction between concrete to concrete. But know the friction coefficient bet. rubber and concrete which is 1.0. Extending the same logic and since the concrete is heavy the static coefficient of friction may be around 1.0. visit...

I would like to know whether it is possible to remove (Uninstall) a program completely without any traces. I mean the data written to processor too. I know programs which can delete registry entries too but not from processor. Any help from you geeks is appreciated. Thanks

You can comfortably use the RISA-3D in your case. I have been using the same for a year and found really good for small to medium FEM idealisations. You can model different curved shapes with spring supports very easily through a wizard. More to say about it is it's GUI which is really great...

The soil characteristics are very well dealt in International Building Code 2000. The acceleration coefficient is calculated based on soil profile (Table 1615.1.1 page 350 of IBC 2000). Whether you have to do static or dynamic analysis depends upon the the type and importance of the structure...
