dear all;
i observe that the problem still appears in current edition,
i got very small capacity along section (c) manly
best;

dear zoi;
i got the problem solved by increasing number of steps but
i got a very weak response even lesser than the original structure
please any help;
best

Dear Zoi;
since i do not extend the steel sheets to the beams/foundation, how could i model that hollow section to get the shear demand imposed on it and not having the the effect of such jacket on the global stiffness?
best

dear seismostruct team;
i used the latter suggestion to model a retrofitting of concrete rectangular section with steel sheets
and i calculate the total shear capacity of the retrofitted section and assign it to the concrete cross section
then i push the structure (the jacketed structure ) using ...

dear all;
i m trying to add some vertical wide-column to existing structure;
i made the Eigenvalue analysis with activation time 0.01 for these new shear wall and i observed that the natural period does not changed , which is expected since the new shear wall is not activated in this stage
then i ...

dear all;
i m wondering why is the value of the shear demand ( and the corresponding capacity for sure as a result ) is getting to be smaller than the step before, since i m expecting the shear to increase as the lateral lode increase (pushover analysis) and because i m not assigning and strength ...

dear all;
how i could see the enhanced section capacity in term of shear for a retrofitted beam ?
i cant see any modification in the shear capacity after retrofitting a beam with 0.001 of sheet using both method:
1- in section module : introducing the FRP jacket
2- as a hollow rectangular section ...

dear Seismostruct team;
i still need a clarification;
any help;
best;

no i did not calculate any, i just use the default value of crushing strain of concrete to check all columns
do i need to calculate any thing ??

dear all;
regarding to the shear capacity criteria implemented in the software, i m observing that the automatic calculated values in "section characteristic" module are being used to check the overall shear strength even when activating the "include the concrete and axial force contribution ...
