Preliminary Structural Design of Wall-Frame Systems for Optimum Torsional Response

Building structures of low or medium height are usually designed with a pseudostatic approach using a base shear much lower than that predicted from an elastic spectrum. Given this shear force, the objective of this paper is to evaluate the effect of the element strength assignment (as determined by several building codes) on the torsional response of inelastic single-storey eccentric structures and to provide guidelines for minimizing this structural behaviour. It is demonstrated that the expected torque about the centre of mass (CM) may be, with equal probability, positive (counterclockwise) or negative (clockwise). This result means that the torsional strength should also be provided in equal terms in both rotational directions, and therefore the base shear and torque (BST) surface of a given system must be symmetrical (or approximately symmetrical). In stiffness-eccentric systems, appropriate BST surfaces may be obtained when a structural design is based on a pair of design eccentricities in a symmetrical order about CM, and this is shown in representative single-storey building models under characteristic ground motions.

Reversed Cyclic

Frame systems are commonly used in structural design. Beams and columns are essential in the design and analysis of these types of structures. Since no practical and generally recognized method has yet been developed to determine the failure loads of these systems, nonstructural components such as architectural walls are not usually taken into consideration in the analyses. In this study, the experimental failure loads and failure types of 30 partially or fully infilled steel frame systems were determined after testing these systems under reversed cyclic horizontal loading. After the analytical study was carried out, the failure loads and failure modes of the samples were obtained analytically using the equivalent strut tie method, and experimental and analytical results were compared.Key words: infilled steel frames, partially infilled frames, lateral load-carrying capacity, equivalent strut tie method.

The Impact

Abstract In this paper, an evaluation was tried for the impact of structural design on structural response. Several situations are foreseen as the possibilities of changing the distribution of the structural elements (sails, columns, etc.), the width of the structure and the number of floors indicates the adapted type of bracing for a given structure by referring only to its Geometric dimensions. This was done by studying the effect of the technical design of the building on the natural frequency of the structure with the study of the influence of the distribution of the structural elements on the seismic response of the building, taking into account of the requirements of the Moroccan earthquake regulations 2000/2011 and using the ANSYS APDL and Robot Structural Analysis software.
