Background of the research: A conventional box-type structure is generally used in constructing core/shear wall, internal frame, and steel box girders. Tube-in-Tube with single multiple tubes reduces shear lag effect lateral deformation a tall tubular structure. Purpose: However, present study focuses on behavior modified form beam, i.e., beam outstanding flanges. Thus, this analyzes flanges co...

The presented research deals with the optimal design of main girder an asymmetric box cross-section double-beam bridge crane. Moth-Flame Optimization algorithm (MFO) is used for solving this multicriteria optimization problem. This a relatively new population-based metaheuristic method. paper takes following criteria as constraint functions: strength, local stability plates (webs and top flange...

The composite strengthening beam combined with a variety of reinforcement technology, complementary advantages.In order to study the mechanical behavior T-beam strengthened CFRP board, external angle steel and prestressed strand, six reinforced test beams were fabricated compare analyze structural characteristics bending stiffness, crack development bearing capacity. research shows that by stra...

The hinge joints of the assembled concrete multi-girder bridge (ACMGB) are main components transverse transmission loads and decline their capacity would lead to degradation cooperative working performance (TCWP) multi-beam system. As key this kind bridges, its severe result in single-girder-bearing phenomenon inducing collapse. In order detect TCWP timely, paper proposes a vibration-based moni...

Due to wood creep characteristics, the failure mode, bearing capacity, stiffness, and deformation of its components are doomed be impacted by long-term loading. This paper conducted a comparative test on beams, regulated short-term beams based former loading research. The results demonstrated that glulam beam experienced tensile beam-bottom, while horizontal joint local compressive beam-end hap...
