Abstract:
ACI 441 and 341 Committees will be co-sponsoring a session on nonconventional reinforced concrete columns/piers during the ACI Spring Convention 2022. This session aims to provide a platform to have understanding the behavior, design, and construction challenges of nonconventional/atypical columns. Challenges from design to constructions related to such columns/piers will be discussed and innovative solutions will be debated for their improved performance. The title of the session is: “Behavior, Design and Construction of Nonconventional/Atypical Reinforced Concrete (RC) Columns/Piers”. Columns/piers that do not fall within the scope of conventional reinforced concrete columns/piers are referred to here as nonconventional/atypical columns/piers. Such structural elements cover a wide range as they can be observed in the present construction practices and various research labs. For example, the use of various composites and alloys as longitudinal and transverse reinforcement other than conventional steel (e.g., fiber-reinforced polymer bars and spirals/stirrups, shape memory alloy bars, stainless steel bars, titanium alloy bars, etc.), special reinforcement arrangement, special concrete type to address specific needs during construction or service life of the column, abrupt changes in the column cross-section within the column length, irregular column heights in bridge bents, unusual structural geometry that leads to complicated load demand on the column, and columns experiencing unconventional loads such as blast and impact loads. The increase in demand for taller buildings, longer span and irregular bridges, longer service life, and shorter construction time impose new challenges on engineers to devise/implement new materials, structural shapes, reinforcement arrangements, and types to meet these demands.
