Evaluation of wind load integration in disproportionate collapse analysis of steel moment frames for column loss

The design of steel structures, in most cases, depends majorly on the level of wind loads which are prescribed by codes and regulations and are used in the structural analysis due to the fact that steel structures being light and ductile systems are strongly affected from a slight difference in the values of wind loading. During the last decades, disproportionate collapse analysis has become of major interest mainly due to the increasing number of failures occurring in that pattern. Commonly accepted guidelines and methods of analysis have been produced, the most dominating of which being the Department of Defense Facilities criteria or DoD. In the DoD, as well as in other criteria, the event of a column loss is suggested as the modeling scenario which has to be sustained by a structural system in order to be robust. However, all the guidelines so far have disconnected the column loss analysis from wind loads and have only performed it for gravity loading. This paper presents the dynamic time history disproportionate collapse analysis of steel frames, including various levels of wind loading. Interesting aspects are discussed through the parametric analysis of five different numerical examples of moment resisting frames.

Effects of plastic hinges on partial interaction behaviour of bolted side-plated beams

Slips of mechanical connectors in steel plate reinforced concrete (RC) structures can significantly affect the load-carrying capacity of the structures. The difference in deformation between the steel plate and the reinforced concrete counterpart is known as partial interaction. In this study, the flexural behaviour of bolted side-plated (BSP) reinforced concrete beams was investigated experimentally. Two new deformation-based parameters, namely the strain factor and curvature factor, were introduced to quantify the degree of partial interaction between the RC beam and the steel plates. The experimental results revealed that the degree of partial interaction between RC beams and steel plates could be reduced by as much as 50% when the BSP beam proceeded from a linear to a non-linear stage in which plastic hinges have formed in critical sections. Consequently, the load-carrying capacity was reduced by up to 30% of the theoretical additional strength provided by the bolt-plate system, which is more than double the allowance proposed previously in the literature. The under-estimation of the effect of partial interaction in composite structures can result in unsafe design.     

Seismic analysis for tall and irregular temple buildings: A case study of strong nonlinear viscoelastic dampers

Viscoelastic (VE) dampers, composed of VE layers sandwiched between relative rigid steel plates, have been widely used as dissipation devices to improve performance of structures under dynamic loads. Corresponding analytical and experimental investigations have been carried out by many scholars. However, most of VE dampers studied before are typically traditional dampers applied in regular structures. This paper introduces a new type of VE damper with strong nonlinearity used in the complex and irregular structure of Nanjing Dabaoen Temple. The new VE dampers show obvious nonlinear behavior, improved capacity of dissipation, and larger additional stiffness compared to the traditional ones. Nanjing Dabaoen Temple is a high‐rise steel structure by use of 112 new VE dampers. To investigate dissipation characteristics and control effect of the VE dampers in the complex structure, we established a suitable finite element model using SAP2000 software in which the VE dampers were simulated by Maxwell and Wen models connected in parallel, and then nonlinear time history analysis is executed using seven ground motions of moderate earthquakes and three of major earthquakes. Analytical results indicate that control effect of the VE dampers on structural displacement is preferable to that on structural acceleration and shear force due to dampers' additional stiffness. In addition, owing to incremental deformation of VE dampers under major earthquakes, damping effect of the VE dampers on all structural responses under major earthquakes is more obvious than that under moderate earthquakes. Analytical methods and conclusions in this paper will provide significant reference for analysis, design, and application of complex high‐rise structures added with VE dampers.
