Abstract

From a structural aspect, the behavior of a castellated beam is not as reliable as that of a solid beam. Hence, the focus should be on improving the behavior of castellated beams. An attempt has been made in this study to experimentally use external prestressing to enhance the behavior of castellated beams. Four beams are fabricated and tested. It is found that the use of pesters over a castellated beam significantly enhances its behavior in all aspects.

Introduction

In a broader sense, two different types of structures rule the world-concrete and steel. The choice between steel and concrete as construction material depends on various factors, including the specific project requirements, budget constraints, design considerations and local building codes. Both materials have their advantages and disadvantages. Steel structures are advantageous over concrete in aspects of strength and durability, speed of construction, design flexibility, lighter weight, adaptability, sustainability, etc. In practice, many construction projects use a combination of both steel and concrete, where each material is best suited to its specific application within the project. Hybrid structures that leverage the strengths of both materials are common and offer a balanced approach to meet project requirements. The choice between steel and concrete should be made after careful consideration of the unique needs of the project. In this paper, the major focus is on steel structures and the area taken up for the study is castellated beams.
