1.054/1.541 Mechanics and Design of Concrete Structures Spring 2004Prof. Oral Buyukozturk 1 / 9Massachusetts Institute of Technology1.054/1.541 Mechanics and Design of Concrete Structures (3-0-9) Outline 9 Beam Column JointsImportance of joint behavior oWeak link theory oDeterioration mechanisms oDetailing Monolithic beam-column jointsoIn the design with the philosophy of limit states it is seen that joints are often weakest links in a structural system. oThe knowledge of joint behavior and of existing detailing practice is in need of much improvement. oJoint behavior is especially critical for structures subject to earthquake effects. oThe shear forces developed as a result of such an excitation should be safely transferred through joints. The R/C system should be designed as a “ductile system”. Design of joints oJoint types Type I – Static loading Æstrength important Æductility secondary Type II – Earthquake and blast loading Æductility + strength Æinelastic range of deformation
