Pozzolans, known to possess high pozzolanic activity, enhances the long-term engineering properties of concrete due consumption calcium hydroxide and consequent formation calcium-silicate-hydrate gels within cementitious matrix. Although key factors that affect activity such as chemical composition, amorphousness, fineness are commonly addressed in literature, there is a growing need further gain an insight into govern this more comprehensive approach. The aim empirical study develop models...

Despite the complex punching shear behavior of reinforced concrete slabs have been comprehensively addressed in literature, it is further essential to develop a universal design model comprising high accuracy and simplicity for practicability, adaptable diverse conditions encountered practice. Artificial intelligence applications, artificial neural networks (ANN), more recently, various machine learning (ML) deep (DL) techniques veer off new direction structural engineering context with...

The comprehension of the threshold for need supplemental dampers in base isolation multistory buildings could be beneficial advancement application to achieve seismic safety. In this study, stick models 1‐, 4‐, 7‐, 10‐, 13‐, 16‐, and 19‐story were designed fixed‐base, simply base‐isolated, damping‐assisted base‐isolated scenarios. system considered is well‐known friction pendulum system, with damping provided by widely used viscous dampers. Time history analyses conducted using seven...

We construct self-similar functions and linear operators to deduce a variant of the Laplacian operator D'Alembertian wave operator. The exigence self-similarity as symmetry property requires introduction nonlocal particle-particle interactions. derive describing dynamics quasicontinuous chain infinite length with spatially distribution interparticle springs. harmonic interactions results in dispersion relation form Weierstrass-Mandelbrot function that exhibits fractal features. also...

Strengthening and rehabilitation have been widely implemented for many years to extend the service life of reinforced concrete structures. The paper begins with a comprehensive review fiber-reinforced polymers (FRP) utilization on strengthening particularly over traditional materials formerly used in practice respect materials, manufacturing, operation, construction, maintenance phases, as well engineering environmental performance such materials. Carbon Glass FRP, most frequently are...

We demonstrate that fractional Laplacian (FL) is the principal characteristic operator of harmonic systems with self-similar interparticle interactions. show FL represents ‘fractional continuum limit’ a discrete ‘self-similar Laplacian’ which obtained by Hamilton's variational principle from spring model. deduce generalized elastic potentials regular representations for involve convolutions symmetric finite difference operators even orders extending standard representation FL. Further we...

We analyse some fundamental problems of linear elasticity in one-dimensional (1D) continua where the material points medium interact a self-similar manner. This continuum with ‘self-similar’ elastic properties is obtained as limit chain harmonic interactions (harmonic springs) which was introduced [19] and (Michelitsch T.M.

Sustainability is considered to be highly important for preserving continued industrial growth and human development. Concrete, being the world's largest manufacturing material comprises cement as an essential binding component strength However, excessive production of due high degree construction practices around world frames a leading pollutant releasing significant amounts CO2 in atmosphere. To overcome this environmental degradation, silica fume hydrated lime are used partial...

A large body of experiments have been conducted to date evaluate the punching shear strength flat slab-column connections, but it is noted that only a few them considered for development ACI Code provisions. The limited test results used code provisions fall short predicting accurately such connections. In an effort address this shortfall and gain insight into factors control we report qualified database 650 in article. All slabs examined were tested under gravity loading do not contain...

Even though fibre reinforced polymers (FRP) have been competently utilised to enhance the punching shear capacity of flat slab-column connections over last few decades, a unified formula addressing influence FRP strengthening on performance such is deficient.
