how to design this link beam
i have a shear wall which has a 5ft by 7ft opening on each floor, we used a link beam with has 10ft depth to connect the opening. now i need to design the concrete beam, anybody has ideas how to design it? is the beam to deep? can i design it as shear wall rotated 90 degree? attached is a sketch of the shear wall and link beam.
thanks all.
try chapter 10 of this reference.
if it is for seismic applications, need to comply with aci ch 21. they give you a diagram of how the rebar need to look. hopefully, you're section is wide enough to do it.
