| dc.description.abstract | In Civil Engineering construction, a variety of materials compete and this is initiating a nonstop
technological invention. This invention not only concerns the enhancement of the materials
themselves but also results in the preface of new technologies and approaches for fabrication,
joining and construction. There's growing interest within the reinforced concrete assiduity in using
advanced-strength construction materials for certain operations. In more recent times, it has been
set up possible to produce steels, at fairly low cost, whose yield strength is 3 to 4 times further
than that of ordinary reinforcing steels. Likewise, it's possible to produce concrete 4 to 5 times as
strong in compression as the further than ordinary concrete. These high-strength materials offer
numerous advantages. At present in our country, high-strength concrete having a compressive
strength of further than 4000 psi is possible and again, advanced strength reinforcing bars with a
yield stress of,72,000 psi are available for structural construction which may reduce the cost of
construction and ameliorate structural safety.
The primary focus of this study is to find out the effects of using different grades of bars on the
responses of high-rise structures towards EQ and Wind and also to compare the structural
performances among them. To achieve this thing, a floor plan, a model of three 20-storied
structures has been done, which is located in Dhaka, Bangladesh. All loads are applied according
to Bangladesh National Building Code (BNBC). All the models have been developed for
analogous lading scripts using the same structural systems. Three structure models have been
created considering 40- grade, 60- grade and 75- grade bars and analogous concrete compressive
strength. Relative studies have been carried out in terms of story relegation, story drift, shear
forces, capsizing moment, stiffness, etc. for all structures and eventually try to present the
configurations which have better performance | en_US |
