Determination of the optimum H/l ratio of hollow arch-bodied steel bricks

As a result of the investigation of difficult construction events such as earthquakes, fires, etc., there is a need for new beam design and calculation in terms of damage to the beams; excess material use, improper construction of cables, ducts, installations. In this research, the standard Hea beam used in the construction was compared with a steel beam with a hollow reinforcing steel beam with a hollow arch body, which had previously been negatively investigated at different heights, and the analyses of a new steel beam with a hollow arch body under the same load at the same heights. Hollow arch steel beams are a type of design and structural component used in structural engineering. These beams are often used to overcome large spans, sometimes not very advantageous in terms of cost, but with the advantage of strength and light weight. The main objective of the research is to calculate a new type of beam that has less weight than the Hea beam but can carry at least the same load. Hollow arch framed beams consist of an upper surface formed by an arch and a beam at the bottom. In the presented beam specimen, the lower cap consists only of abutments and is designed as a bridge arch beam The beam is designed with a cavity under the top surface, which provides lightness to the structure and is architecturally aesthetically pleasing. The hollow part is designed and structured to reduce weight and reduce material costs. For the beams, s235jr steel material was used and all analyses were carried out with ansys software program. In the abutments of the beams analysed, anchored bearing, which is a type of bearing that provides resistance to all horizontal and vertical loads and moments from both sides, was applied. In addition, the anchored bearing prevents all kinds of movement and rotation. At the same time, the results of the analyses with different bearings for the new beam were shared. The beams are 1000-1500 mm long and the same force (2,1447e + 006 N) is applied for each of them. The new beam specimen is 460 kq lighter than the hea beam and shows better resistance to the same load. The analysis of the new beam specimen with a length of 1500 mm shows that it is less heavy than the 1000 mm specimen, but more resistant.
