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...

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

Column strengthening is a very common practice for improving the seismic performance of reinforced concrete frame structures or repairing damage after event. Several methods are employed column strengthening, which can improve strength by preventing its shear, bending compression failure. However, not all allow connections between adjacent floors, thus beam-column joint could be limited column-...

We propose a left-to-right (i.e., from the most significant column to the least significant column) algorithm for computing a signed-binary (SB) representation of pairs of integers with minimum joint weight as well as maximum average length of zero-column runs. The proposed method speeds up the scalar multiplication of elliptic curve cryptosystems (ECC) by all known strategies, while at the sam...

Glue joints are more useful in Aerospace so in this article we presented new method for glue joint. In this method the maximum stresses that occurs at the edges of the bottom glue joint and cause ultimate failure in this type of connection is Decrease and increase the glue joint strength. In this method glue in the area overlapping the discrete and separate column considered Also, the connectio...

The October and November 2004 HHN Accreditation Strategies columns addressed the new Joint Commission on Accreditation of Healthcare Organizations (Joint Commission) home care and hospice survey process describing in detail components of each survey activity. This column builds on the foundation laid in the two columns and focuses on survey process nuances for complex organizations, specificall...
