Push-out tests on shear studs in high strength concrete
A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedd...
متن کاملA Study on Behaviour of Normal Strength Concrete and High Strength Concrete Subjected to Elevated Temperatures
Cement concrete is a complex mixture of different materials. Behaviour of concrete depends on its mix proportions and constituents when it is subjected to elevated temperatures. Principal effects due to elevated temperatures are loss in compressive strength, loss in weight or mass, change in colour and spall of concrete. The experimental results of normal concrete and high strength concrete sub...
متن کاملA COMPREHENSIVE STUDY ON THE CONCRETE COMPRESSIVE STRENGTH ESTIMATION USING ARTIFICIAL NEURAL NETWORK AND ADAPTIVE NEURO-FUZZY INFERENCE SYSTEM
This research deals with the development and comparison of two data-driven models, i.e., Artificial Neural Network (ANN) and Adaptive Neuro-based Fuzzy Inference System (ANFIS) models for estimation of 28-day compressive strength of concrete for 160 different mix designs. These various mix designs are constructed based on seven different parameters, i.e., 3/4 mm sand, 3/8 mm sand, cement conten...
متن کاملImproving Non-Destructive Concrete Strength Tests Using Support Vector Machines
Non-destructive testing (NDT) methods are important alternatives when destructive tests are not feasible to examine the in situ concrete properties without damaging the structure. The rebound hammer test and the ultrasonic pulse velocity test are two popular NDT methods to examine the properties of concrete. The rebound of the hammer depends on the hardness of the test specimen and ultrasonic p...
متن کاملOn Applicability of Some Indirect Tests for Estimation of Tensile Strength of Anisotropic Rocks
The tensile strength of rocks plays a noteworthy role in their failure mechanism, and its determination can be beneficial in optimizing the design of the rock structures. Schistose rocks due to their inherent anisotropy in different foliation directions show a diverse strength at each direction. The purpose of this work was to compare and assess the tensile strength of phyllite, which was obtai...
