Applying PIANC Fender Design Guidance to US Design Codes

By: William Bruin, Julie Galbraith, Rune Iversen, Maximo Argo
This paper provides a proposed rational approach for marine terminal designers in the United States to accompany the PIANC document and apply the factors outlined within it to standard US design codes. In addition, this paper provides commentary on the various topics covered within the PIANC guidance to provide some additional clarity and updated information based on the latest information and research for various topics.

Evaluation of Marine Structures for Kinematic Effects

By: William Bruin, Julie Galbraith, Muhammad Naeem

In performance-based seismic design, a marine structure is designed for inertial loading effects associated with the dynamic response of the structure. Some waterfront structures also experience seismically induced kinematic effects, associated...

Experimental Evaluation of a Procedure for SMF Continuity Plate and Design

By: Adel Mashayekh, Chia-Ming Uang

The AISC Seismic Provisions require that continuity plates in a special moment frame (SMF) welded moment connection be connected to the column flanges by complete-joint-penetration groove welds. Tran et al. (2013) have proposed a design procedure...

Experimental Evaluation of a Procedure for SMF Continuity Plate and Weld Design

By: Adel Mashayekh, Chia-Ming Uang
The AISC Seismic Provisions require that continuity plates in a special moment frame (SMF) welded moment connection be connected to the column flanges by complete-joint-penetration groove welds. Tran et al. (2013) have proposed a design procedure that allows the designer to evaluate the required forces in the continuity plates such that more economical welds (e.g., fillet welds) can be used; the required thickness of the continuity plates also need not be the same as that prescribed in the AISC Seismic Provisions.

Digital Design, Coordination and Delivery

By: Matthew Johnson
Methods for digital design, coordination, and delivery are prevalent in the building design and construction industry. As tools and knowledge evolve, new software applications present themselves on a broad range of projects. Modeling software is especially relevant to structural designers, who can use the software to optimize material quantities, improve coordination, and streamline execution for project with complex geometry.
