Dynamic response of simply supported beams excited by piezoelectric actuators
… and understand the force transfer mechanism in beams and plates, and in this work an adaptation of a published model is presented, and compared with experimental data and other published models. The force transfer mechanism between the piezoelectric actuator and the beam is found to be dependent …

Resistência ao esforço cortante de peças de concreto armado de seção transversal circular
… with circular cross-section are presented. Eight simply supported beams with a 3,0 m span and a 0,4 m diameter cross-section were tested by loading them with two symmetrical concentrated forces. The variable parameters were the distance from one of the concentrated force to the nearest support and …

Optimization of Reinforced Concrete Structures
… reinforcement. Design examples include simply supported beams, continuous beams and small frames. From a practical standpoint the method developed can be a valuable tool for design of reinforced concrete structures.

An investigation into the material behaviour of reinforced concrete beams
… the material behaviour of reinforced concrete beams is presented. This investigation is divided into two parts. First, the experimental load-deflection tests on eleven under-reinforced two-span- and four slightly over-reinforced simply-supported beams are presented. The finite element …

Strength of beam-columns in flexibly connected steel frames.
… incorporating flange cleat connections the beams and columns can sustain greater loading and deflect less than is predicted by current design models. The assumptions of pin-ended columns and simply supported beams are shown to be conservative. Comparisons of the results of the column and …

Object oriented programming for reinforced concrete design
… the flexural capacity of reinforced concrete tee beams was developed in both languages. A second program for the analysis and design of reinforced concrete continuous beams was developed in Actor and C++. This application is representative of a practical structural engineering application and has …

MATLAB implementation of an operational modal analysis technique for vibration-based structural health monitoring
… responses from two finite element models of simply-supported beams and their modal frequencies and shapes were extracted. The first three modal frequencies were obtained with less than 6 percent error from the actual values and the fundamental mode shape values obtained contained negligible …

Bridge-vehicle interaction for structural health monitoring: potentials, applications, and limitations
… on Single Degree of Freedom linear system, simply supported beams. The novel Delay Vector Variance (DVV) methodology has been employed for characterization of structural behaviour by time-domain response analysis. Also, the analysis of responses of actual bridges using DVV method has been …

STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues
… was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. Steel bars were modelled as an elastic perfectly plastic material, with perfect bond between …

Behaviour of High- and Ultra-High Performance Fibre Reinforced Concrete Flexural Members
… including fibre-reinforced concrete (FRC) simply-supported beams, ultra-high performance fibre reinforced concrete (UHPFRC) continuous beams, curved beams, skew slabs and also sandwich panels using ultra-high performance concrete (UHPC) face sheets, are experimentally studied. Having …

Shear strengthening of pre-cracked and non pre cracked reinforced concrete continuous beams using bi directional CFRP strips
… the shear strengthening of reinforced concrete simply supported beams using FRP composites. However, strengthening continuous beams in shear have received very little attention among the researchers although most of the existing structures are in the form of continuous condition. Furthermore, …

Comparative study on the behaviour of concrete reinforced with FRP and steel singly reinforced beams
… work consisted of testing a total of 5 simply supported beams, each tested under four-point loading until failure. One beam consisted of steel reinforcement, three beams consisted of the Carbon Fiber Reinforced Polymer (CFRP) reinforcement, the other beam had CFRP with an experimental …

Physics-Informed Neural Networks for Structural Health Monitoring of Bridges
… to noise and modelling imperfections. For simply supported beams under moving loads, forward PINNs are developed using spatial–temporal inputs, and then extended to include axle load magnitude as an additional input. These models accurately reproduce deflection, moments and strains for …

Flexural Behaviour of Geopolymer Concrete T-beams Reinforced with FRP or Hybrid FRP/Steel bars
… the flexural behaviour of geopolymer concrete T-beams reinforced with GFRP or Hybrid GFRP/Steel bars. To achieve this aim, twelve geopolymer concrete flanged beams reinforced with various combinations with steel and GFRP bars were experimentally tested, and comprehensive computational finite …

Influencia de la distribución de la carga en la capacidad resistente a cortante en elementos sin armadura transversal : estudio teórico y experimental
… fitting of experimental results dominated by simply supported beams subjected to point loading, the distance from the support to the load being greater than 2.5 times the effective depth of the elements. It is also observed that most tests are carried out using reinforcement ratios very much …
