Abstract:
This study aims to investigate the joint strength of longitudinal plate-to-high-strength steel circular hollow-section X-type joints under plate axial load. The material properties of high-strength steel with nominal yield strengths of 460, 650, 900, and 1100 MPa were used for parametric analysis. The variables for analysis were ratios of chord diameter to thickness, plate width to chord diameter, and utilization. To determine the capacity of connections, the joint strengths using a deformation limit and a strength limit were considered and compared with American Institute of Steel Constructio

Abstract:
ABSTRACT The number of buildings higher than 30 floors has shown remarkable growth; many of them are supported on foundations of hollow circular piles. This increasing of height of constructions causes an increment of the shear stresses that are transmitted to their foundations, however these elements are more shear critical due to the hollow core. Most of the existing codes are based on shear models for rectangular sections, and guidelines for assessment of shear strength of members with hollow circular cross sections are practically non-existent. This study evaluates, on a comparative basis,

It is well known that the confinement effect provided by the steel tube significantly increases the strength and ductility of circular Concrete Filled Steel Tube (CFST) columns under concentric loading. The lateral pressure is an important factor to calculate the strength enhancement of CFST columns. To reliably predict the ultimate strength of circular CFST columns, many models have been developed for predicting the lateral pressure due to the confinement effect. This paper aims to evaluate some of these confining pressure models. The values of the compressive strength of confined concrete an

In recent years, high-strength concrete (HSC) has gained a more widespread acceptance in the construction industry. In spite of the advantages inherent to HSC, concerns still exist about its relative brittleness, particularly in regions of high seismic risk. An experimental and analytical investigation was conducted to study the behaviour of circular HSC columns subjected to simulated seismic loading. The experimental program included the testing of nine full-scale circular columns under combined axial compression and lateral load reversals. The emphasis was on the strength and deformation cha

Circular Concrete Filled Tubes are gaining importance in the construction industry due to their advantages insofar as economy and structural efficiency. Due to the recent developments in concrete and steel technology, the usage of high strength materials in these concrete filled tubes is increasing.

Abstract : Circular reinforced concrete (RC) members are often used in civil engineering structures, for instance, as piers and piles in bridge substructures. Also, their applications are frequently utilized as a fender and piling system for harsh water front and marine environments. Such members are usually reinforced with conventional steel bars and stirrups. Corrosion of steel reinforcement constitutes one of the major problems that shorten the lifetime serviceability and, hence, brittle failure of many concrete structures worldwide.

In this framework, the use of agricultural waste materials promotes waste reduction and eco-design in plastic product manufacturing. This study researched the preparation of an isotatic polypropylene (PP) matrix (MFI 50 grade) with spent coffee grounds (SCG) and various commercial additives. The biocomposites were analyzed to evaluate their mechanical properties and processability. PP and SCG composites were synthesized with 30% SCG content with maleic anhydri

Abstract:
Biaxial shearing tests on dual-sized, 2d particle assemblies are conducted at several confining pressures. The effect of particle angularity, an important mesoscale shape descriptor, is investigated at the macro and micro levels. Macroscopically, it is observed that assemblies composed of angular particles exhibit higher strengths and dilations. The difference observed in bulk behavior due to particle angularity can be explained reasonably by considering particle-level mechanisms. A novel 2D image analysis technique is employed to estimate particle kinematics. Particle rotation results to be a

Abstract:
This working paper shows how Maldives can boost recycling to strengthen its solid waste management strategy, protect its blue ocean economy, and create green business opportunities to support its long-term sustainable growth. Estimating under 2 percent of plastic waste is recycled in the island nation, it outlines how factors including high costs, inefficient collection efforts, and a lack of reprocessing facilities are hobbling recycling efforts. It recommends Maldives set up public-private partnerships with waste exporters and recyclers, incentivize domestic demand, and build a modern waste

Status quo, trends, and policy options for the Austrian and European light-weight community, with a focus on mobility.

Abstract:
Lightweight construction, as a set of cross-sectional technologies, has the potential to contribute to several challenges, which are prevalent now and in the near future. Starting from the mobility sector, which has traditionally been a key driver for innovation for lightweighting, it has the potential to contribute to resource and energy efficiency in a broad set of sectors and locations as long as it does not contradict, i.e., complies with the principles of a circular economy. This study investigates lightweight construction in Austria. For that purpose, we identify relevant actors in Austr

Abstract:
"Today, more than 70% of global production for key critical minerals is concentrated in just a few countries, raising serious concerns about supply security, market volatility, and geopolitical risk. Achieving a just and sustainable energy transition hinges on fair and reliable access to critical minerals—materials key for low-carbon technologies. However, global supply chains remain environmentally damaging and vulnerable to geopolitical tensions, creating systemic risks for both climate and economic goals. • A Global Minerals Trust offers a new multilateral model to promote responsible stewa

Abstract:
20 years ago a concept of “Green Chemistry” was formulated by Paul Anastas and John Warner, aiming at an ambitious agenda to “green” chemical products and processes. Today the concept, laid down in a set of 12 principles, has found support in various arenas. This diffusion was supported by enhancements of the legislative framework; not only in the European Union. Nevertheless industry actors – whilst generally supporting the idea – still see “cost and perception remain barriers to green chemistry uptake”. Thus, the questions arise how additional incentives as well as measures to address the ba
