Dear iceman84 & mig21,
[ Topic 1]
For example, in the last step of pushover, appear red hinge ( indicate failure ) in beam.
The questions :
1) How I know this failure is flexure failure or shear failure ?
---
If the failure is shear failure :
2a) Does etabs already connect with etabs concrete design so that etabs already consider the shear capacity of concrete with shear reinforcement based on shear demand of element ( beam in this case ) ?
---
2b) Or etabs only "read" this beam as "pure concrete" ( concrete without shear reinforcement, because we can not add shear reinforcement ), then still need check separately as you told to me ( check shear capacity of concrete manually or use etabs conc. design & compare with shear force at a step of pushover ) ?
---
[ Topic 2]
I need suggestion based on your experience, do I need locate the "shear" pushover-hinge at both ends plus at mid span of beam/column OR only at both ends of beam/colum ?
---
Thanks for your time & your answers
Regards
Paladin
