Combining GPR, Passive Seismic, and Load Testing With Computational Models in the Assessment of Historical Bridges: The Case Study of the Comboa Bridge

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The preservation of historical bridges usually requires extensive structural evaluations for possible damage detection. Therefore, effective techniques are essential for diagnosis and, consequently, proper maintenance and rehabilitation actions. The combination of techniques provides complementary data that support decision making.

Distributions of non‐native and native plants are not determined by the same environmental factors

Ecological Solutions and Evidence, Volume 5, Issue 4, October–December 2024.
Distributions of non‐native plant species are driven more strongly by anthropogenic variables than distributions of native plant species, though climate is the most powerful predictor in both species groups. Species distribution models should therefore be fitted with different variables based on the study species' degree of nativeness.

Effect of CFRP Sheets Strengthening Method on Behaviour of Modified Lightweight Foamed Concrete Beams

Journal of Engineering, Volume 2024, Issue 1, 2024.
This study has been adopted to examine the effect of carbon fibre‐reinforced polymer (CFRP) sheet strengthening methods on the flexural behaviour of modified foamed concrete beams reinforced with different steel reinforcement ratios, and it deals with the enhancement in flexural behaviour of conventional nonstrengthened FC beams. Twelve modified foamed

Experimental and Numerical Analysis of Omnidirectional Steel Moment Connection With Through‐Plate Panel Zone Under Cyclic Loading

Shock and Vibration, Volume 2024, Issue 1, 2024.
This paper proposes a new beam to column connection, namely, the omnidirectional steel moment connection with through‐plate panel zone, which enables the connection of more than four beams to a column in moment frames at any arbitrary angle. The proposed connection was experimentally and numerically analyzed under cyclic loading.

Modified interactive strut-and-tie model for shear strength prediction of RC corbels

Engineering and Applied Science Research, 2019
On the basis of the modified Kupfer and Gerstle’s biaxial failure criterion ofconcrete, amodified interactive strut-and-tie model (MISTM) to predict the nominal shear strength of RC corbels was derived and is proposed in this paper.

Numerical analysis of reinforced concrete dapped-end beams [PDF]

Revista IBRACON de Estruturas e Materiais
The reinforced concrete dapped-ends present in beams, being regions of discontinuity, require non-trivial models for their analysis and design, such as the strut-and-tie model, the shear-friction model, and the finite element method.
