Steel Frame Structure

Purpose Progressive collapse because of high temperatures arising from an explosion, vehicle impact or fire is an important issue for structural failure in high-rise buildings. Design/methodology/approach The present study, using ABAQUS software for the analysis, investigated the progressive collapse of a two-dimensional, three-bay, four-storey steel frame structure from high-temperature stresses. Findings After structure reaches the temperature results like displacement, stress axial load and shear force are discussed. Research limitations/implications Different temperatures were applied to the columns at different heights of a structure framed with various materials. Progressive collapse load combinations were also applied as per general service administration guidelines. Originality/value This study covered both steady-state and transient-state conditions of a multistorey-frame building subjected to a rise in temperature in the corner columns and intermediate columns. The columns in the framed structure were subjected to high temperatures at different heights, and the resulting displacements, stresses and axial loads were obtained, analysed and discussed.

Design Case Study

Purpose This paper aims to discuss fire safety design of single-story, single compartment buildings and evaluates whether time to structural damage is a relevant criterion when lethal fire conditions develop long before any structural fire damage can occur. Design/methodology/approach The proposed approach is demonstrated in a design case study of a steel truss in a typical Swedish single-story steel frame building. Findings While not complying with deemed to satisfy fire resistance ratings, it is argued that the proposed design still can fulfill the life safety objective. Originality/value This paper presents practical application of a conceptual paper presenting a general approach to structural fire safety design and the life safety objective.

This paper presents the importance of the second-order effects in behaviour of steel frame structures. EN 1993-1-1 were distinguished three main methods: taking / without taking into account second order effects depending on the sensitivity of horizontal design effects and tolerance. Using these methods, the susceptibility of steel frame structures to second-order impacts is considered in accordance with EN 1993-1-1. The study was performed taking into account also the rotational stiffness of the joints of the frame structure. In this way, trying to determine the effect of the joint on the rotational rigidity makes the frame structure more sensitive to second order impacts. It is also considered a semi-rigid joints effects the general frame-tailed P-Δ and the second row stress. This establishes the link between the effects of the second-order and the semi-rigid joints in the overall (general) analysis. Frame-building sensitivity makes it possible to compare and measure the importance of such dependencies.

Since the appearance of the first modern multistories buildings, besides the demand of ensuring the bearing capacity, one of the urgent problems facing the engineer is to do how to design structure to ensure the requirements of normal use such as displacement, motion acceleration within permissible limits. There exist many methods to reduce these response of structure under lateral load. Among these, using fluid viscous damper (FVD) is one of the most applied equipment because of its simplicity. This paper presents the examination of eight-story steel frame structure subjected to seismic load. The FVD system is defined in Etabs with link properties. In each story, four dampers are located in each direction of plan, with two on each side of the center of stiffness of the story. The time history analysis was conducted to study the structure subjected to seimic load collected from the function library of program Etabs. The effect of FVD system was determined by the dynamic response of the building and displacement indexes such as maximum displacement of roof, story drift ratio. The results show that, all the dynamic response characters of structure were decreased significantly when providing the FVD to it.
