Abstract:
This is the second in the series of Q&A articles attempting to clarify some common questions and misconceptions about glass fiber-reinforced polymer (GFRP) reinforcing bars. Discussed topics include traceability, hybrid reinforcement, sustainability, elevated temperature and fire, seismic provisions, limitations, and splices and headed bars.

Glass fiber-reinforced polymer (GFRP) reinforcement is currently only allowed to be used in concrete structures in Seismic Design Category (SDC) A. An approach explored in this article is the use of GFRP reinforcement for structural elements that are not intended to be part of the inelastic (yielding) mechanism of the seismic force-resisting systems.

This article explores the evolution of Indonesia's concrete design codes, and how a foundation was built through decades of engagement with ACI standards. Through the Indonesian Society of Civil and Structural Engineers (HAKI) and ACI's shared commitment to excellence, a code born from colonial, Dutch origins evolved into a modern standard tailored to Indonesia's seismic realities.

Current nonlinear modeling software for concrete frames typically employs line elements with plastic hinges defined at user-selected locations. While this is a simple and computationally efficient approach, a number of drawbacks limit its application. They include the challenges with defining the interacting shear and moment hinge curves, uncertainties with hinge locations and lengths, and difficulties in capturing the post-peak response. Two-dimensional continuum methods address these limitations, but their computational cost limits their applicability. This study presents an alternative modeling method, and associated computer software, with the objective of combining the simplicity of frame elements with the accuracy and result visualization capabilities of continuum methods. The method, developed in the last two decades, employs a distributed-plasticity, layered-section approach based on the Disturbed Stress Field Model (DSFM). The distributed-plasticity approach eliminates the need for defining plastic hinges while the DSFM enables capturing the shear, moment, and axial force interaction. The total-load and secant-stiffness formulation provides numerically stable solutions, even in the post-peak region. This paper presents an overview of the theoretical approach, unique aspects, and capabilities of this method. The validation studies undertaken for 148 experimental specimens, subjected to static (monotonic and cyclic) and dynamic (impact, blast, and seismic) load conditions, are also presented.

This article describes trends observed between measures of building robustness and observations of performance collected after 15 earthquakes. It provides comparisons between countries that followed the Japanese preference for “stiff” structures and those that build less-stiff structures and discusses implications of the latest field observations in relation to the future of reinforced concrete practice.
