The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

A safety-based evaluation of strut-and-tie methods for shear design of RC deep beams in accordance with international concrete codes

Engineering and Applied Science Research, 2020
On the basis of strut-and-tie models (STMs) in accordance with international concrete codes such as ACI 318-14, AASHTO LRFD, CSA A23.3, Eurocode2 and fibMC 2010, a safety-based evaluation of shear design methods for RC deep beams was performed and is ...

Strut elaboration in strut-and-tie model

Constructii: Journal of Civil Engineering Research, 2012
The Strut-and-Tie Model (STM) has been incorporated into the codes and standards because of its consistency and rationality since last decade. However, it has encountered few challenges whilst its implementation. The effective compressive strength of strut has been a complex issue among researchers since emergence of STM.

Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Structural Performance of RC Beams containing Tension-Only Nodes

International Journal of Concrete Structures and Materials, 2018
Strut and Tie (S&T) models are used for the design of what are known as “discontinuity regions” in reinforced concrete (RC) structures. Building codes such as ACI-318 and Eurocode 2 do not give information on the nodes that only connect ties in S&T ...

Refinement of Strut-and-Tie Model for Reinforced Concrete Deep Beams

PLOS ONE, 2015
تُستخدم العوارض العميقة بشكل شائع في المباني الشاهقة والهياكل البحرية والأساسات. وفقًا للعديد من الرموز والمعايير، يوصى باستخدام نموذج الدعامة والربط (STM) كنهج عقلاني لتحليلات العارضة العميقة. يركز هذا البحث على STM الموصى به من قبل ACI 318-11 و AASHTO LRFD ويستخدم النتائج التجريبية لتعديل عامل فعالية الدعامة في STM للعوارض العميقة للخرسانة المسلحة ...

‘From the Fields Into the Bars’: The Story of Israel's First Transgender Novel, The Cut (1977)

Gender &History, EarlyView.
ABSTRACT In 1977, an Israeli transgender woman, Judy Spotheim, published an autobiographical novel entitled The Cut. It describes the emergence of a trans community in the commercial‐sex areas of Tel Aviv‐Jaffa, hoping to humanise trans women (coccinelles). This article is the first to study the novel and present a biography of Spotheim.

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.
