Book Description
This volume contains papers of the 9th European Workshop on the Seismic Behaviour of Irregular and Complex Structures (9EWICS) held in Lisbon, Portugal, in 2020. This workshop, organized at Instituto Superior Técnico, University of Lisbon, continued the successful three-annual series of workshops started back in 1996. Its organization had the sponsorship of Working Group 8 (Seismic Behaviour of Irregular and Complex Structures) of the European Association of Earthquake Engineering.This international event provided a platform for discussion and exchange of ideas and unveiled new insights on the possibilities and challenges of irregular and complex structures under seismic actions. The topics addressed include criteria for regularity, seismic design of irregular structures, seismic assessment of irregular and complex structures, retrofit of irregular and complex structures, and soil-structure interaction for irregular and complex structures. Beyond an excellent number of interesting papers on these topics, this volume includes the papers of the two invited lectures – one devoted to irregularities in RC buildings, including perspectives in current seismic design codes, difficulties in their application and further research needs, and another one dedicated to the challenging and very up to date topic in the area of seismic response of masonry building aggregates in historical centers. This volume includes 26 contributions from authors of 11 countries, giving a complete and international view of the problem.The holds particular interest for all the community involved in the challenging task of seismic design, assessment and/or retrofit of irregular and complex structures.

Book Description
Headed reinforcing bars are becoming more popular in the construction industry; however, there is relatively little known about the interaction of the head and bond in resisting loads. As such, the ACI 318-08 (the 2008 version being the current version) code equation governing headed reinforcing bars appears to be a gross generalization of the capacity of a headed bar. The purpose of this project was to study the contributions of the head and bond as they change with varying bond lengths, clear covers, and head bearing areas to determine if a better model can be developed to represent a headed bar. Twelve headed bar specimens were cast, each one with a unique combination of bone length, clear cover, and head bearing area, and loaded until failure. Two failure modes were observed: bar yielding and side blowout. The loads resisted by the head and bond throughout the loading of each specimen were analyzed for trends. It was determined that headed bars follow one of two patterns: head-dominated and bond-dominated, and is dependent on bond length. As such, different models should be used for the capacity of each pattern. The specimen capacities were compared to models proposed by others, and the current ACI 381-08 code equation. The ACI 318-08 code equation was found to be a good fit with a minor modification for the bond-dominated bars. It was determined to not be possible to develop a model for head-dominated bars from this test program and that additional testing must be conducted.
