Non-Linear Behavior of New (FSFN) Moment Resisting Connections in Comparison to the Existing KBB Connections in Steel Frames

After Northridge (1994) and Kobe (1995) earthquakes, several studies have been conducted to improve the seismic performance of steel structures. In this investigation, new steel moment-resisting connections (FSFN) developed by the authors, were studied by the non-linear numerical analysis. These connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-...

Guest Editor\'s Note

Although Occupational Therapy in Iran is relatively a new profession, it has been well progressed, providing various services for people with all kinds of disabilities. As such, in the last decades, OT has been recognized as the major demand in all governmental, private and NGO sectors. Due to this demand, occupational therapy training programs have been increased from three into ten, expecting...

Editor's Note

This issue comes with changes in our web page and the addition of a group of scholars who have graciously accepted to be our advisory board members. PLSJ was a challenge in Persian studies in Iran and was faced with quite a few obstacles in these five volumes. The ministry of higher education still does not consider PLSJ as an academic journal and does not list in its approved list of journals!...

Happy New Year 2019, and welcome to Conference of Iranian Medical Journal Editors

Mathematical Modeling of Column-Base Connections under Monotonic Loading

Some considerable damage to steel structures during the Hyogo-ken Nanbu Earthquake occurred. Among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. The lessons from these phenomena led to the need for improved understanding of column base...
