The finite element models of biaxial shear capacity of RC frame columns are investigated.The calculation results and experimental results are compared using the different models.It is shown that different finite element models are effectively used to simulate the RC frame column. However, the simplified model may save computer time and be more convenient for the numerical simulation. Finally, the bilateral shear correlation of RC frame column is investigated using the simplified model.

Abstract:
An overall numerical model for a reinforced concrete frame was established and in parallel, a group of simplified models were established for the same structure according to the particular characteristics of the subjected load such as impact load, dynamic load and quasi-static load, to investigate their dynamic behaviors. Results show that it is reasonable to introduce the simplified models for reinforced concrete frame in analysis work.

Abstract:
Significant progress in the finite-element (FE) modeling at the member-level of reinforced-concrete (RC) structures under seismic excitation has been achieved in the past decades; however, reliable and accurate analysis models for full-scale 3D system-level RC structures validated with experimental data are scarce. As the development of a complete nonlinear model is expensive and time consuming, simpler models, typically elastic or lumped-plastic in nature, are employed in practice with additional provisions prescribed to account for nonlinear behavior. Depending on the assumptions made by the

Abstract:
The use of dynamic resistance–capacitance (RC) grey-box models to estimate building thermal energy demands is a well-known strategy. Nonetheless, there are no clear methodologies to generate model variations without having to re-identify the parameters that are simple, flexible, accurate and low computation demanding. This research introduces a simple methodology that combines parameter identification from white box generated data and simplified theoretical building thermal equations to create functional and reliable RC model variations from an original grey-box model.

Abstract:
In the modelling of reinforced concrete (RC) buildings, the rigid diaphragm hypothesis to represent the in-plane behavior of floors was and still is very commonly adopted because of its simplicity and computational cheapness. However, since excessive floor in-plane deformability can cause a very different redistribution of lateral forces on vertical resisting elements, it may be necessary to consider floor deformability. This paper investigates the classical yet intriguing question of modeling orthotropic RC floor systems endowed with lightening elements by means of a uniform orthotropic slab

Abstract:
It is known from previous experiments that the load-carrying capacity for RC slabs at large deflection is governed and enhanced by the tensile membrane action. However, due to the intrinsic complexity of concrete properties, it is hard to capture the history of the load-deflection relationship for RC slabs. After reviewing several analytical reinforced concrete models, the author develops a simplified load-displacement semi-analytical model for laterally unrestrained simply supported RC slabs. Three stages have been identified for this model, which are elastic stage, transition stage and pure

Abstract:
Reinforced concrete (RC) tanks are essential for storing liquids and bulk materials across various industries. However, simplified analytical methods fall short in providing an accurate analysis, while traditional methods, such as finite element modeling, can be computationally intensive and time-consuming, especially when dealing with nonlinear material properties and complex geometries, like conical and cylindrical shapes. This highlights the need for a more efficient and simplified analysis approach. Accordingly, the present paper introduces a machine learning (ML) framework as an effective

Openings in reinforced concrete (RC) beams may be required due to building installations (electrical, water, etc.).

The paper evaluated the influence of rectangular openings on the Fire Resistance Rating (FRR) of RC beams by the Simplified Method of NBR 15200.
