    Abstract: To afford extra built-up space vertically both for working and living, high-rise buildings are constructed. Living in high-rise buildings has advantages as well as disadvantages. On the constructive side high-rise buildings can accommodate more people closer to work places, thus decreasing the length of work journeys and energy consumption. When we... Show More

    Abstract: In practice cured concrete strength may exhibit strength variation from batch to batch and within batch despite the mixes being of the same proportions and with quality control. On the other hand, structural concrete elements are designed to meet specific characteristic strength. In order to ensure compliance to the specified characteristic strengt... Show More
