Plastic sand paver blocks provide a sustainable alternative by using plastic waste and reducing the need for cement. This innovative approach leads to more construction sector promoting environmental preservation. No model or Equation has been devised that can predict compressive strength of these blocks. study utilized gene expression programming (GEP) multi-expression (MEP) develop empirical models forecast (PSPB) comprised plastic, sand, fibre in an effort advance field. The database...

Plastic waste poses a significant hazard to the environment as result of its high production rates, which endanger both and inhabitants. Similarly, another concern is cement, accounts for roughly 8% global CO2 emissions. Thus, recycling plastic replacement cementitious materials may be more effective strategy minimisation cement elimination. Therefore, in this study, (low-density polyethylene) utilised sand paver blocks without use cement. In addition this, basalt fibers green industrial...

Plastic sand paver blocks (PSPB) provide a sustainable alternative by reprocessing plastic waste and decreasing reliance on environmentally hazardous materials such as concrete. They promote management favorable building practices. This paper presents novel method for estimating the compressive strength (CS) of based gene expression programming (GEP) techniques. The database collected from experimental work comprises 135 results. Seven input parameters were involved in predicting CS PSPB,...

Abstract Concrete compressive strength is usually determined 28 days after casting via crushing of samples. However, the design may not be achieved this time-consuming and tedious process. While use machine learning (ML) other computational intelligence methods have become increasingly common in recent years, findings from pertinent literatures show that gradient-boosting ensemble models mostly outperform comparative while also allowing interpretable model. Contrary to comparison with model...

Abstract Reinforced concrete (RC) short columns have suffered significant damage during past earthquakes, demonstrating a brittle shear failure. Many design codes lack specific equation to estimate the capacity of RC columns; consequently, engineers relied on existing equations for ordinary beams and columns. However, it has been shown that these do not accurately This study aims develop feedforward neural network model predict under uni-directional seismic excitation. A dataset consisting...

In this study, a neuro-wavelet technique was proposed for damage identification of cantilever structure. At first, localisation accomplished through mode shape decomposition using discrete wavelet transforms. Subsequently, indicator defined based on the detail coefficients decomposed signals. It found that distinct patterns relate indicators to locations. Considering property, neural network ensemble developed quantification. Damage and locations were selected as input parameters networks....

Abstract Simplicity and computational efficiency of the lumped plasticity model have made it a popular approach for analyzing structures. However, has been shown by researchers that accuracy representing inelastic behavior reinforced concrete (RC) structures needs further investigations. Two full‐scale RC frames with different shear spans were constructed subjected to vertical load through their beam. Finite element (FE) models tested specimens established in SAP2000 software, results...

In recent years a new strengthening technique that includes the addition of thin layer made steel-fiber-reinforced concrete (SFRC) over precast slabs has been introduced. The desired structural performance for this method can only be achieved if SFRC overlay and slab behave compositely. research, effects using different substrate treatments on composite behavior strengthened by an are evaluated through experimental tests. addition, advantages disadvantages topping conventionally reinforced...
