The fire resistance of steel framed multi story buildings and their ability to withstand

exposure to fully developed fire conditions without the need for all structural members to be

Due to the limitation of computer capacity and the soften of the material constitution, the nonlinear dynamic earthquake analyses of skyscrapers are not practical in engineer’s desktop, and even in the research area they are still open problems. Utilizing ABAQUS’s unique combination of implicit and explicit technologies and capable of solving large problem efficiently, the author solves the problem elegantly and practically. In the analysis model, all members and shear-walls are modeled by plastic zone model, and large deflection effects are taking into account.

The National Transportation Safety Board (NTSB) investigates accidents to identify the probable cause and to make recommendations that would prevent similar accidents. Following the collapse of the I-35W bridge in Minneapolis on August 1, 2007, the NTSB worked with the Federal Highway Administration, the Minnesota Department of Transportation and other parties with information and expertise, including SIMULIA Central, to determine the circumstances that contributed to the collapse of the bridge, completing the investigation in 15 months.

There are plans of constructing bridges longer span like Messina strait bridge. This

trend causes the necessity of discussing on the problems of instability analysis such as lateraltorsional buckling. However, lateral torsional buckling analysis of long span bridge is not

sufficiently taken yet. For that reason, we apply the Abaqus/Standard to solve the high nonlinear problem. The analysis object is Akashi-kaikyo Bridge which is the longest bridge in the world. This paper presents how to analyze the lateral-torsional buckling of long span bridge applying wind load.

Abaqus is often applied to solve geomechanical boundary value problems. Several Abaqus built-in features enable a wide range of simulating such problems. For complex problems Abaqus can be extended via user subroutines. Several extensions for soil mechanics purposes are discussed and corresponding case studies are presented.

Conical piles of granular solids can be found in many industrial sites. These piles are

This research involves a failure analysis of the internal structural collapse that occurred in World Trade Center 5 due to fire exposure alone on September 11, 2001. It is hypothesized that the steel column-tree assembly failed during the heating phase of the fire. Abaqus/Standard was used to predict the structural performance of the assembly when exposed to the fire. Results from a finite element, thermal-stress model confirms this hypothesis, for it is concluded that the catastrophic, progressive structural collapse occurred approximately 2 hours into the fire exposure.

This paper aims to investigate the train-induced ground vibration and appropriate

Compared with response spectrum method and the pushover method, Elasto-plastic dynamic time-history analysis method is considered to be a more accurate seismic analysis method. Because of Abaqus’s strong non-linear calculation function, the software makes it possible for the method mentioned above to be applied. Elasto-plastic dynamic analysis on complex structures using Abaqus has a rapid development in China.

The connected structure refers to the kind of building which is composed of two or more

towers connected by the connecting body in a certain height, belonging to the irregular building

structure system. According to “Technical Specification for Concrete Structures of Tall Building”
