Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

Structural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Optimizing UHPC Layers to Improve Punching Shear Performance in Concrete Slabs

Buildings
Flat slabs supported by columns without beams are widely used in construction owing to their economy and efficiency. However, brittle punching shear failure at slab–column connections can cause progressive collapse.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Optimal structural design method for reinforced concrete column in buildings with high floor heights using a genetic algorithm

Structural Concrete, EarlyView.
Abstract Globally, there is a growing trend toward taller, larger, and more structurally diverse buildings that require expansive interior spaces. Rapid technological advancements have surged the demand for data centers, while the expansion of e‐commerce has increased logistics volumes, driving the need for large‐scale warehouses.

Punching shear of unbonded post‐tensioned steel fiber reinforced concrete slabs: The fiber contribution

Structural Concrete, EarlyView.
Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

Deformation and strength of grouted sleeve connectors in pre‐fabricated concrete structures: Mechanisms and analytical modeling

Structural Concrete, EarlyView.
Abstract Grouted sleeve connectors (GSCs) are widely used in precast/prefabricated concrete structures. To ensure force transfer, connectors are often overdesigned in length. This practice has an unintended consequence of reducing the plastic deformation capacity of the connection region and hence the displacement ductility of the precast structure as ...
