Abstract: - There are many details for reinforced concrete
frame joints. Few of these details could satisfy the strength
requirements, cracking and ductility. But the joint are still the
weakest part in structural system. Observations made after
earthquake, accidental loading shows that breakdown at the
joint is the most frequent cause of failure of element connected.
Distribution of stresses at an opening corner indicates that high
tensile stresses exist at the inner corner normal to diagonal,
coupled with tensile stresses along the diagonal. This paper
explains the objectives to strengthen the joint to avoid the
tensile stresses which causes the diagonal cracks at the joint.
Five types test models are considered to analysis having
different attachment to the corner for strengthening purpose.
The models are subjected to heaviest load. Analyzed by using
Stad-pro. The solid steel plates are found as an outstanding
solution but attachment is very difficult. Chamfering is also
helpful to this condition but cracks are developed in this case.
The two angular plates are used to avoid diagonal cracks.2017-06-02T00:00:00Z
