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

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation

Structural Concrete, EarlyView.
Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...

Assessment of shear reinforcement enhancement on the punching shear capacity of flat concrete slabs with openings

Structural Concrete, EarlyView.
Abstract Reinforced concrete flat slabs are widely employed in contemporary architecture due to their structural efficiency and construction simplicity; however, their susceptibility to punching shear failure remains a critical design concern, particularly at slab–column connections where concentrated loads occur.

Behavior predictions of deep beams with short straight bar anchorages using strut-and-tie models and nonlinear analysis

Revista IBRACON de Estruturas e Materiais
This paper investigates the laboratory test results of 12 deep beams available in the literature, where the longitudinal reinforcement was anchored into the support using short straight bar anchorages.

Strut-and-tie modelling of deep beams [PDF]

, 2019
A modified strut-and-tie model for deep beams was developed. Several significant improvements were made and gave rise to better prediction performance of deep beam shear strength, evaluated by 233 test results. No empirical stress limit was required and the concrete softening effect was embedded in the model.

Dual potential capacity model for short and deep reinforced concrete members containing steel fibers

Structural Concrete, EarlyView.
Abstract This study presents an analytical model for estimating the shear strength of short and deep steel fiber‐reinforced concrete (SFRC) members with a shear span‐to‐depth ratio less than 2.5. To this end, a dual potential capacity model (DPCM) is developed based on the demand‐capacity approach for evaluating the shear strength of SFRC beams that ...

Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones

Buildings
The strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Reliability analysis of strut-and-tie models for the design of deep beams according to NBR 6118 (2023) [PDF]

Revista IBRACON de Estruturas e Materiais
The strut-and-tie method (STM) applied in the structural design of deep beams is a semi-probabilistic method, that does not take directly into account both the uncertainties associated with the variables involved and those inherent in the calculation ...

Shear capacity of reinforced concrete corbels using mechanism analysis [PDF]

, 2012
A mechanism analysis is developed to predict the shear capacity of reinforced concrete corbels. Based on shear failure observed in experimental tests, kinematically admissible failure mechanisms are idealised as an assemblage of two rigid blocks ...
