Modification for Ductile Detailing of Beam Column Joints
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Earthquake resistant buildings are necessary to reduce the damage caused to structures during devastating earthquakes. One of the characteristics of earthquake resistant buildings is having an adequate design on the beam-column joint. Generally, when large forces occur during earthquakes, joints are severely damaged which endangers the entire structure. Seismic design focuses on the ductility of a frame as the main structure to resist the lateral force. The beam–column joints with inadequate or no transverse shear reinforcement have proved deficient and are likely to experience brittle shear failure during earthquake motions. So ductile detailing of a beam column joint is very important for its better performance under the seismic loads. But it is noted that the anchorage requirements for the beam longitudinal reinforcement bar and the joint confinement are having main issues related to problems of congestion of reinforcement in the beam–column connections. There are lots of practical difficulties in the execution of such conventional designs. With the development of new technologies and materials alternatives for these conventional types of joint reinforcement is possible. The project focuses in the design and analysis using the software ANSYS 15, for an alternative joint reinforcement with better or equivalent performance. An attempt has been made to evaluate the performance of the exterior beam– Column joint by replacing the 90° standard bent bar anchorages By T-type mechanical anchorage.
