Modular steel bridges are structures whose construction is based on regular prefabricated truss units. This presents several advantages, such as rapid and easy deployment, high adaptability to the terrain reduced costs. However, they generally face operational restrictions for span lengths greater than 60m. Recent technological innovations search overcome these limitations develop modular with ...

response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...

steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...

In recent past, the authors developed an innovative modular system for low rise building made by structural sandwich panels. This was conceived with focus on rationalization of construction process and thermal efficiency building. Thus, precast panels comprise two outer Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) layers, a insulation material Glass Polymer (GFRP) connectors. Studie...

The fundamental periods of buildings are essential to calculate the design base shear and lateral forces. Most seismic codes specify empirical formulae to estimate the fundamental vibration period of buildings. These empirical formulae are used for both lowand mediumrise buildings. These formulae depend on the building materials (steel, reinforced concrete etc), building types (frame, shear wal...

Abstract In this research, an attempt has been made to evaluate the structural response of multi‐storey composite modular buildings when subjected lateral wind loads. Finite element (FE) models were developed in Abaqus for a general 10 storey building, with and without consideration load resisting mechanisms shear walls. Concrete filled steel tubular (CFST) columns walls proposed place conventi...
