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 ...

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 ...

A New Punching Shear Equation of Normal and High Strength Reinforced Concrete Flat Slabs

Journal of Engineering and Sustainable Development, 2012
The aims of this study is to present a new simple accurate equation to determine the punching shear strength of normal and high strength reinforced concrete flat slabs. The punching shear strength prediction of the proposed equation is compared with the

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

Artificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical

‘Be There, Listen, See What It Is They Need’: Fathers' Roles in Supporting Black Mothers During Pregnancy

Child &Family Social Work, EarlyView.
ABSTRACT There is a critical public health crisis regarding the infant mortality rate between black and white mothers in the USA. This issue is more pronounced in North Carolina, where black infants have a much higher infant mortality rate than whites.

Disposable negative pressure wound therapy system enhances punch graft acceptance in equine distal limb wounds

Equine Veterinary Education, EarlyView.
Summary This case series describes the use of a disposable, canister‐free negative pressure wound therapy (NPWT) system (PICO®) in combination with punch grafting for the treatment of distal limb wounds in three horses. Each horse presented with complex traumatic injuries resulting in delayed or inadequate healing of distal limb wounds.
