Steel ordinary moment frames (OMF) are seismic force-resisting systems that can be used in buildings. In current seismic design and detailing provisions, such as the American Society of Civil Engineers ASCE/SEI 7-10 (2010) , American Institute of Steel Construction ANSI/AISC 341-10 (2010), and ANSI/AISC 358-10 (2010) , less stringent design and detailing requirements are specified for steel OMFs compared with those for steel special- and intermediate-moment frames. The strong-column weak-beam (SC/WB) requirement is not enforced for steel OMF connections. In the present study, the seismic performance evaluation is conducted for steel OMFs designed according to current seismic design and detailing provisions considering different combinations of gravity, seismic, and wind loads, as well as wind drift limits. Based on the results of seismic performance evaluation, permissible structural heights for steel OMFs are also proposed.

A reduced beam section with a bolted web (RBS-B) connection is permitted for use only in intermediate moment frames (IMF) according to the ANSI/AISC 358-05. This is because some RBS-B test specimens failed to achieve 4% total rotation capacity, which is the minimum story drift angle required for special moment frames (SMF). Several studies reported that some RBS-B connections could experience brittle connection fracture during earthquakes, which can also be detrimental to the seismic performance of IMF systems with RBS-B connections. For investigating whether IMFs with RBS-B connections provide a satisfactory seismic performance, this study evaluated the seismic performance of IMFs with pre-qualified RBS-B connections following the ATC-63 procedure. Twenty-four model buildings were designed according to current seismic design provisions. Several IMFs with RBS-B connections do not satisfy the acceptance criteria specified in ATC-63.

It is known that buried polyethylene (PE) pipes exhibit good seismic performance owing to their flexibility and ductility. The use of PE pipes as buried pipelines is gradually increasing, but currently, there are no seismic design or seismic performance evaluation procedures for domestic PE pipes in Korea. In this study, a seismic design and performance evaluation procedure for a domestic fusion-type PE pipe was developed based on the response displacement method, which is relatively easy to apply. The procedure was based on a method of examining whether the sum of the axial strain induced by both normal and seismic loading was within the allowable strain of the PE pipe. While calculating the axial strain of the ground, a coefficient was introduced to account for the heterogeneity of the ground. A seismic review method for ground deformation, i.e., ground liquefaction, was also introduced. The proposed procedure will provide a useful technical basis for evaluating the seismic design and performance of buried PE pipes in future studies.
