ABSTRACTComposite construction is advantageous due to the combination of steel and concrete materials in structural members. Composite column’s cross-section types such as hexagonal, octagonal, and decagonal and high diameter-to-thickness (D/t) ratios are highly desirable in transmission towers, yet not covered in the applicable codes. Therefore, the objective of this study is to investigate the behavior of composite columns with various characteristics including cross-section types, and height and propose a design procedure based on Force – Moment (P-M) Interaction diagrams and related equations. Three-dimensional non-linear finite element models were developed using a nonlinear finite element software to simulate and verify the behavior of the composite towers against prior experimental work. Concrete Damage Plasticity and Steel Bilinear Elasto-Plastic Model were calibrated and used in capturing the realistic nonlinear behavior of the materials and their interaction. Based on the computational models, a concrete reduction factor, needed for the development of design equations, was derived. Conclusively, typical normalized P-M Interaction diagrams were constructed for various polygonal shapes with high D/t ratios beyond code limitations. The corresponding derived design equations play a significant role in the applicability of the composite columns in transmission towers.KEYWORDS: Compositeconcrete damage plasticitynonlinear analysistransmission towersP-M diagrams List of symbols used in the manuscript Symbol=Descriptionγ=concrete strength reduction factorE=Modulus of Elasticityν=Poisson’s ratiof’c=Concrete Compressive Strengthɛ=Strainσ=StressKc=Shape of the yield surfacefbo=Initial biaxial compressive yield stressfco=Initial uniaxial compressive yield stressr=Total section radiusrc=Concrete section radiusd=Outer depth of the sectiondc=Inner depth of the sectiont=Steel section thicknessAs=Steel section areaFy=Yield stressZ=Section modulush=Distance from top of the section to depthDisclosure statementNo potential conflict of interest was reported by the author(s).

ABSTRACTHigh-performance concrete (HPC) is currently widely utilised in the civil engineering and construction industry. The rising use of HPC in structural applications, as well as the necessity to justify fire resistance, has prompted numerous laboratories to research high-temperature characteristics. The relevant properties of HPC with polypropylene fiber (PPF) and fly ash (FA) were determined through an experimental study. This paper presents some key aspects related to compressive strength for High-Performance Fiber Reinforced Concrete (HPFRC) with and without FA at high temperatures ranging from 100°C to 800°C for use in fire resistance calculations. Visual investigation revealed a change in colour as the temperature rose. It may be used as a guide for maintaining, designing, and predicting the life of HPC structures, such as high-rise buildings that are exposed to high temperatures. Detailed research on the mechanical and durability characteristics like the workability of fresh concrete, as well as compressive strength, modulus of elasticity, drying shrinkage, water permeability, and sorptivity coefficient of hardened concrete containing PPF and FA is also reported in this paper. FA concentration in concrete mixtures was 0%, 10%, 20%, 30%, and 40% on a mass basis, with fibre volume fraction ranging from 0% to 0.3% on a volume basis.KEYWORDS: High-performance fiber reinforced concretepolypropylene fiberfly ashdrying shrinkagewater permeabilitysorptivity Disclosure statementNo potential conflict of interest was reported by the author(s).

ABSTRACTThe corrosion of reinforcement possesses a huge problem for our present infrastructure both in terms of human lives and monetary ground. Understanding the corrosion of thermomechanically treated (TMT) rebar in concrete structures is essential as it represents a large segment of reinforcement materials. In this review, we have tried to scrutinize this issue from different directions. The established corrosion model for rebar, especially for TMT rebar, has been examined. The main contributing factor for rebar corrosion is how passivation occurs and its disintegration in contact with aggressive ions. The effects of composition, microstructure, concrete-rebar interface, concrete type, and corrosion media on this phenomenon have been analyzed. We have realized that the exact time of chloride ion attack determines the effectiveness of the passive layer in inhabiting the corrosion initiation. A combination of suitable alloying and controlled thermomechanical treatment ensures corrosion resistant rebar. Concrete also plays an important role in corrosion prevention as it helps passivation step and stops aggressive ions from reaching the rebars. Finally, we have discussed some recent trends in corrosion management technologies and their effectiveness.KEYWORDS: CorrosionTMT rebarreinforcementRCC structuresthermo-mechanical treatmentpassivation AcknowledgmentsThe authors would like to thank the Bangladesh University of Engineering and Technology (BUET) for providing assistance with different facilities.

In this paper, a set of concrete beams with different cementitious binders are designed and tested to investigate the time-dependent deflection of concrete beams subjected to flexural load over a period of 1 year. Test parameters mainly included the effect of cementitious binders (silica fume (SF), ground-granulated blast-furnace slag (GGBS), and a combination of SF and GGBS), and polypropylene fibers on the time-dependent deflection of concrete. The specimens used in this study are under drying/unsealed conditions. The drying condition was designed to obtain the combination of the creep and the shrinkage that occurred in the common practice of construction. One of the most important problems in the repair of flexural members of concrete structures is the problem of creep and shrinkage, which is a relatively unknown problem in the literature. Furthermore, the experimental results are selected to validate the proposed models. Prediction of time-dependent deflections under flexural loading is proposed by the inverse analysis (IA) method. Based on the results, in comparison to the control specimen, the long-term deflection increases of 5.9% and decreases of 22.1% and 43.2% for specimens containing GGBS, SF and a combination of SF and GGBS, respectively, at the test age of 383 days.
