Performance-Based Optimization for Strut-Tie Modeling of Structural Concrete [PDF]
, 2002 Conventional trial-and-error methods are not efficient in developing appropriate strut-and-tie models in complex structural concrete members. This paper describes a performance-based optimization (PBO) technique for automatically producing optimal strut ...

Ecological Entomology, EarlyView.First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Numerical analysis of reinforced concrete dapped-end beams [PDF]
Revista IBRACON de Estruturas e MateriaisThe 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.

Evaluation of strut-and-tie modeling for bridge pier applications [PDF]
, 2002 Strut-and-tie modeling is an analysis and design tool for reinforced concrete elements which assumes that internal stresses are transferred through a truss type mechanism.

Journal of Anatomy, EarlyView.Aging of bone density (BV/TV) is regional: Forelimb [left] elements gain bone sporadically (orange) but hind limb elements [right] lose bone globally (blue). Abstract Globally, human population structure is quickly trending older, increasing the prevalence and systemic burden of age‐related skeletal disorders such as osteoporosis.

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles
Revista IBRACON de Estruturas e Materiais, 2020 : Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress

Experimental Verification of Strut and Tie Model Design Method [PDF]
ACI Structural Journal, 2007 Although strut-and-tie models (STM) appear to provide safe, lower-bound designs for irregular concrete members, there have not been many experimental validations of them. This paper presents the result from two series of testing of STM specimens. In the first series, 6 specimens having different reinforcing designs but the same overall geometry and ...

10th East Asia-Pacific Conference on Structural Engineering and Construction: Materials, Experimentation, Maintenance and Rehabilitation (EASEC-10) [PDF]
, 2006 This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced ...

Experimental Physiology, EarlyView.Abstract Aortoiliac occlusive disease affecting the abdominal aorta and iliac arteries is conventionally treated with open surgical repair and is the mainstay of treatment. Endovascular techniques have become a less invasive alternative, especially for high‐risk patients.
