Permissible Heights Proposed for Steel Ordinary Moment Frames

초록

Steel ordinary moment frames (OMF) are often used in building construction as a seismic force-resisting system. Among three types of steel moment frames specified in seismic design provisions such as ordinary (OMF), intermediate (IMF), and special moment frames (SMF), design and detailing requirements specified for steel OMFs are the least stringent. To evaluate the seismic performance of steel OMFs, OMFs were designed according to current seismic design and detailing provisions considering different combinations of gravity, seismic, wind loads, as well as wind drift limits. FEMA-P695 was used for seismic performance evaluation. Then, permissible heights for steel OMFs are proposed based on the results of seismic performance evaluation. 
