Abstract:
In some design cases, such as in castellated beams, cellular beams, or steel beams with expanded web, it is advantageous to strengthen and enhance the performance of steel beams by increasing the web depth. However, expanding the web of a steel beam is a unique engineering strategy. This modification not only enhances its ability to bear heavy loads but also reduces any bending or flexing while enabling longer distances between supports. The expanded steel beams can be achieved by making a horizontal cutting in the steel beam web and then adding an increment plate (with the same web thickness)

Abstract:
The expanded web depth of steel beams leads to improved strength and stiffness. In some design scenarios, such as cellular, castellated, or expanded steel beams, increasing the depth of the web improves the strength and performance of the steel beam. The expanded web of steel beams can be accomplished by creating a horizontal cutting in the web and then adding a plate between the two web section halves, which are called spacer plates. This method leads to improved stiffness and strength. Numerical models have been developed to accurately predict the properties of these beams. This study invest

Abstract:
In this paper, for a wide application of high-performance steel fiber reinforced expanded-shale lightweight concrete (SFRELC) in structures, the shear behavior of reinforced SFRELC beams without web reinforcements was experimentally investigated under a four-point bending test. Twenty-six beams were fabricated considering the influencing parameters of SFRELC strength, shear-span to depth ratio, longitudinal reinforcement ratio and the volume fraction of the steel fiber. The statistical analyses based on the foundational design principles and the experimental results are made based on the shear

Abstract:
This research delves into the structural performance of castellated steel beams featuring expanded webs, emphasizing how design variables, such as the number of openings and cutting angle, affect the load capacity, deflection, and stiffness. Castellated beams are engineered to improve the strength-to-weight ratio of the standard I-beams by cutting and reconstructing the web into hexagonal, rectangular, or circular openings. This configuration not only boosts the beam load capacity and minimizes weight, but also maintains or enhances stiffness, rendering it well-suited for long-span structures.

Abstract:
“Castellated beam” is a name commonly used for type of expanded beam. Castellated beams combine beauty, versatility, economy in steel design. These are fabricated from standard rolled section and are engineered to save time of construction, enabling saving in steel and reducing building costs. These are mainly designed to reduce weight and at the same time increase the efficiency in structural performance. The principal advantage of castellation is the increase in vertical bending stiffness castellated beams have proved to be efficient for moderately loaded longer spans where the Design is con

Currently, the castellated steel beams are used widely because of their useful structural applications and serviceable performance due to their good significant properties such as light weight, facility in construction, materials economize and strength. The castellated steel beam fabricated from its origin solid beam (I-beam) by cutting its web in a zigzag path and then re-joined the two halve by welding so the height of the castellated beam expanded about 50%.

Abstract:
Nowadays, use of castellated steel beams (CSBs) has become very common because of their advantageous implementations in construction of buildings. Castellated Steel Beams (CSBs) are those members that are fabricated from standard hot rolled steel (HRS) I- sections by cutting along its web in "zigzag" pattern and thereafter rejoining the two halves on one another by welding together to form a castellated beam, so that generally the depth of  a section will be increased. This research analyses the experimental results of six specimens of castellated steel beams and compares with control beam (P

This thesis presents the work completed on the evaluation of the expanded web beam concept. The research focussed on investigating methods for expanding the web of a standard pultruded GFRP I-beam to achieve improved mechanical performance whilst achieving an overall saving on mass. The 14 (102 x 102 x 6.4mm) beam was chosen as the standard beam from which the beams were constructed and the mechanical performance of the larger 18 (203 x 203 x 9.5mm) beam as the target for the modified beams. Three designs were proposed and two full-scale beams were built and tested. Of the three designs propos

Abstract:
Cellular beams became increasingly popular as an efficient structural form in steel construction since their introduction. Their sophisticated design and profiling process provides greater flexibility in beam proportioning for strength, depth, size and location of circular holes. The purpose of manufacturing these beams is to increase overall beam depth, the moment of inertia and section modulus, which results in greater strength and rigidity. Cellular beams are used as primary or secondary floor beams in order to achieve long spans and service integration. They are also used as roof beams bey
