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 ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, Volume 128, Issue 3, Page 480-493, September 2026.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Modified Strut-and-Tie Model for RC Deep Beams Considering Size Effect and Longitudinal Reinforcement

Buildings
Accurate prediction of the shear capacity of reinforced concrete (RC) deep beams remains challenging due to the complex interaction of multiple load transfer mechanisms and the pronounced size effect in quasi-brittle materials.

A Comprehensive Review and Analysis of Shear Strengthening of RC Beams with External Prestressing Bars [PDF]

预应力技术
Shear failure in reinforced concrete (RC) structures, characterized by their sudden and brittle nature, often results from inadequate shear reinforcement or degradation due to aging or increased loading demands.

Prediction of the behavior of reinforced concrete deep beams with web openings using the finite ele

Alexandria Engineering Journal, 2014
The exact analysis of reinforced concrete deep beams is a complex problem and the presence of web openings aggravates the situation. However, no code provision exists for the analysis of deep beams with web opening.

Application of micro truss and strut and tie model for analysis and design of reinforced concrete structural elements [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2010
Generally structural members can be broadly divided into two regions, namely B or Bernoulli regions where the strain distributions are linear, and D or disturbed regions where the strain distributions are nonlinear.

Nonlinear structural analysis using strut-and-tie models

, 2005
Increasing popularity of the strut-and-tie methodology among research communities and practising engineers is due to its rational analytical approach and its superiority, compared to the conventionally employed empirical methods for analysing disturbed ...
