Dear Er Suresh ji

I appreciate your attitude for raising very pertinent queries on sefi for all of us to
think deeply as result of your in- depth thinking about structural aspects. I further
...

Yes - - - - As stated in earlier post ,Truss with rigid (welded) joints can be
designed on STAAD SPACE model It will require about 10-15% higher
requirements due to joint rigidity.

Bolted and ...

Still as a layman's view - - -

I think Tall structures vibrating in Ist Mode (like a pendulum) have chances of toppling
and have to be seen for OT check under MCE.
In other modes of dynamic mo ...

A] If loads are not acting at Joints

The truss members are subject to bending as well as axial forces combined and truss
will be costlier.

Finer particles provide more surface area for chemical reaction and 53 Grade
Cement is finer than 43 grade.Hence early gain in strength as rightly enlightened
by Er naga.

P-Delta Effect
As a personal thinking,
both the phenomenons are as result of Axial force multiplied with lateral deflection
of member.In one case (P-Delta)member drifts due to global effects un ...
