The proposed design provisions include composite action of a high-strength concrete (HSC) girder with normal-strength Concrete (NSC) deck slab. Nine 40-ft-long (12m) AASHTO Type II HSC girders were tested with and without cast-in-place NSC decks of differing widths to achieve various possible modes of failure. The concrete used for the girder was designed for three target compressive stregths of 10 ksi, 14 ksi, and 18 ksi (69 Mpa, 97 MPa, and 124 Mpa). The experimental program investigated failure modes of three different types of compression zones: one with NSC only, one with HSC only, and one with both NSC and HSC. All girders were tested to failure under static loading to study the different limit-state behaviors, including prestress losses, initiation of cracking, yielding, and final failure mode.}, number={5}, journal={PCI JOURNAL}, author={Choi, Wonchang and Rizkalla, Sami and Zia, Paul and Mirmiran, Amir}, year={2008}, pages={54–69} }

An available crash test is modeled and the impact response was simulated through a finite element (FE) model. On the basis of insight gained through this detailed FE analysis, a simpler rigid body model is then used to perform a comprehensive study of the barrier response under vehicular impact. The results from FE simulation and the rigid body model are found to be consistent with each other and in good agreement with the full‐scale crash test. On the basis of results from a series of simpler analyses, a set of charts for assessing the barrier displacement and related variables are developed for the purpose of design. }, number={6}, journal={COMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING}, author={Ulker, M.

The present study evaluated the implications of using FRP as primary and sole reinforcement for concrete structures in seismic regions through an experimental and analytical investigation on the cyclic response of two different types of laminated glass FRP tubes filled with concrete. The study showed that concrete-filled tubes can be designed with an appropriate laminate structure for a ductility level comparable to that of conventional reinforced concrete columns. The nonlinearity and ductility in these types of structures stem from the off-axis response of the FRP tube. A hysteretic model was developed for the tube, and was cast into a two-dimensional three-node combined fiber element for the concrete-filled FRP tube. Good agreement was shown between the analytical models and the experimental results.}, number={1}, journal={COMPOSITE STRUCTURES}, author={Shao, Y and Mirmiran, A}, year={2004}, month={Jul}, pages={91–101} }

This paper presents a unique framework for a probable life-cycle cost assessment model for composite materials in construction. The proposed model utilizes the historical life-cycle performance data for conventional materials, knowledge about material properties, and deterioration characteristics for new and conventional materials to effectively assess the life-cycle cost and behavior of composite materials in construction. The proposed model integrates deterioration characteristics of structural components under different environmental and loading conditions to establish performance envelopes. Monte Carlo simulation models are generated to evaluate various maintenance, repair, and rehabilitation (MR and R) strategies possible over the life-cycle. The life-cycle cost associated with each scenario is computed, at different discount factors, to obtain the optimum life-cycle cost for various material options. The specifics of the model are illustrated through an example. }, number={15}, journal={JOURNAL OF REINFORCED PLASTICS AND COMPOSITES}, author={Hastak, M and Mirmiran, A and Richard, D}, year={2003}, pages={1409–1430} }

The model utilizes the double power law creep function for concrete in the framework of rate of flow method, and the linear viscoelastic creep model for FRP. It follows geometric compatibility and static equilibrium, and considers the effects of sealed concrete, multiaxial state of stresses, creep Poisson’s ratio, stress redistribution, variable creep stress history, and creep rupture. The model is verified against previous creep tests by the writers on FWCC and CFFT columns. It is then used to study the practical design parameters that may affect creep of FRP-confined concrete under service loads, or lead to creep rupture at high levels of sustained load. Creep of FWCC is shown to be close to that of sealed concrete of the same mix, as the effect of confinement on creep of concrete is not very significant. CFFT columns, on the other hand, creep much less than FWCC, mainly due to axial stress redistribution. As the stiffness of the tube increases relative to the concrete core, larger stress redistributions take place further reducing the creep. However, there is a threshold, beyond which, stiffer tubes would not significantly lower the creep of concrete. Creep rupture life expectancy of CFFT columns is shown to be quite acceptable.}, number={11}, journal={Journal of Engineering Mechanics}, author={Naguib, W. and Mirmiran, A.}, year={2003}, pages={1308–1319} }

The model adheres to geometric compatibility and static equilibrium, and considers the effects of sealed concrete, multi-axial state of stresses, creep Poisson’s ratio, stress redistribution, variable creep stress history, and creep failure of the column. The model is verified against previous creep tests for bonded and unbonded specimens. A study is then carried out on the practical design parameters that may affect creep of CFT columns under service loads, or lead to their creep rupture at high levels of sustained load. The study indicates that creep of CFT columns should be considered in the design, however, with creep coefficients much lower than those prescribed in the current ACI. Creep of CFT is shown to be a function of concrete mix, column geometry, and interface bond. Therefore, a single ultimate creep coefficient cannot be used for all concrete mixes, column geometries, and construction types. Bonded tubes curtail creep of concrete much more than the equivalent unbonded ones, mainly because of the stress relaxation phenomenon, which is more pronounced for smaller diameter-to-thickness ratios. For diameter-to-thickness ratios of 40 or less, bonded tubes are more durable in creep rupture than the equivalent unbonded ones. Creep rupture life of 75 years is quite feasible in bonded CFT, with diameter-to-thickness ratio of 40 or less, for sustained loads as high as 65% of the static capacity of the column.}, number={11}, journal={JOURNAL OF CONSTRUCTIONAL STEEL RESEARCH}, author={Naguib, W and Mirmiran, A}, year={2003}, month={Nov}, pages={1327–1344} }

Bank, Editor! sponsored a survey of the civil/structural engineering programs around the world on the subject of fiber reinforced polymer ~FRP! composites, excluding the traditional steel-concrete composite construction and fiber reinforced concrete. This paper summarizes the main results from the survey. During the last decade, considerable focus has been devoted to the use of FRP composites in construction. The main driving force is the need for revitalizing the aging infrastructure with innovative materials and structural systems that last longer and require less maintenance. As the construction industry embraces FRPs in the field, the need for educating civil engineers with background on the subject has become more evident. Despite a significant number of field applications and laboratory research, the survey shows that FRPs have not yet been fully implemented in the engineering curricula, and the classrooms are still lagging behind. To improve this situation, civil engineering and their extension programs must provide sufficient training on unique features of FRPs so that engineers could design or specify them in construction. This survey should be repeated as a gauging tool again at the end of this decade.}, number={3}, journal={Journal of Professional Issues in Engineering Education and Practice}, author={Mirmiran, A. and Bank, L.

Field driving of concrete-filled composite tubes showed no damage to the tube or concrete. Driving stresses in filled tubes were found comparable to those for prestressed concrete piles. Empty tubes may buckle or rupture under driving impact, unless driven at shallow depths and in soft soils, or with a steel mandrel. A detailed parametric study using the wave equation further confirmed that there is no difference in the drivability of filled FRP tubes and prestressed concrete piles of the same cross-sectional area and concrete strength. The typical refusal rate for conventional concrete piles can be safely adopted for filled tubes. However, empty tubes are susceptible to compression failure, and can only endure diving stresses up to 40–50% of the refusal rate of concrete piles.}, number={2}, journal={COMPOSITE STRUCTURES}, author={Mirmiran, A and Shao, YT and Shahawy, M}, year={2002}, month={Feb}, pages={127–135} }

While creep effects reduce the flexural stiffness of CFFT specimens, ultimate strength is not significantly altered. The slow rate of loading and short-term creep at 70% of static capacity may cause premature rupture of the tube. Fiber analysis of CFFT beam-columns by discretizing the section into filled and hollow FRP tubes can adequately simulate the flexural creep behavior. Isochronous sustained stress-creep strain curves are used as a constitutive nonlinear relationship for creep analysis in flexure. Creep deflection of CFFT beam-columns is much less than that of CFFT beams, mainly because axial compressive loads tend to retard the cracking of concrete and tensile creep of FRP. The stiffness ratio of FRP tubes with respect to the concrete core has a pronounced effect on the creep deflection of CFFT beam-columns. As the stiffness ratio increases, creep deflection decreases. However, there exists a threshold beyond which stiffer tubes do not provide additional benefit. CFFT beam-columns under high levels of sustained axial loads have a lower creep rupture life expectancy, mainly because failure moments under large axial forces are lower. The creep rupture life expectancy of CFFT beam-columns with diameter-to-thickness ratios of 40 or less is at least 50 years at transverse loads as high as 60% of the static capacity.}, number={4}, journal={Journal of Composites for Construction}, author={Naguib, W. and Mirmiran, A.}, year={2002}, pages={272–279} }
