Behaviour of traditional Portuguese timber roof structures [PDF]

, 2006
The aim of this paper is to present the results of a structural analysis of common trusses traditionally used in roof construction in Portugal. The study includes the results of a preliminary survey intending to assess the geometry, materials and on site

Improvement and Application of the Softened Strut-and-Tie Model

IOP Conference Series: Materials Science and Engineering, 2017
Previous experimental researches indicate that reinforced concrete beam-column joints play an important role in the mechanical properties of moment resisting frame structures, so as to require proper design. The aims of this paper are to predict the joint carrying capacity and cracks development theoretically.

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

Development of strut and tie models for simply supported deep beams using topology optimization [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
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 While well defined theories are ...

Applications of truss topology optimization in the design of reinforced concrete structures using „Strut and Tie” models

Budownictwo i Architektura, 2013
Although Strut and Tie models are often used in practical design due to their apparent concept based on truss analysis, the creation of a model consistent with behaviour of the real structure is not an easy task.

Application of strut-and-tie model on eccentric columns

Mechanics, 2011
The popular strut-and-tie model is currently de fined by EC2 as a standard tool for simple structures. This paper explores the possibility of application of the strut and-tie model on more complex structures, specifically on the eccentric columns. Comparison with full numerical simulation shows that the strut-and-tie model can correctly predict the ...

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

Structural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

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 ...

An efficient 2-way shear grillage model solution for bridge RC four-pile caps under wall loading [PDF]

, 2019
Reinforced concrete four-pile caps under wall loading occur in heavily loaded foundations in bridge construction. The failure mode of shear across the full width of the cap may occur in these deep structural elements.

‘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.
