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”

During the BIW concept developing phase, some key design variables, such as rails and pillars width and position, shell thickness, etc, and multi-attribute responses from safety, NVH, and durability are considered to explore the design space. Isight DOE design drive is used to assess the impact of the variables on the objectives, and this helps the engineer to better understand the design space and give design recommendation. Approximations component is used sequentially to create fast-running surrogate models to replace the real CAE simulations.

In dynamic analysis of NPP civil structures the most suitable method proved to be the method of direct integration of equations of motion of the structure-soil system. This method takes account of geometrically nonlinear effects and dashpots with high level of attenuation. In addition, this method allows for receiving a highly effective solution for some types of NPP civil structures. However, the analysis of resultant response spectra has showed a high level of spectral accelerations at elevations of equipment arrangement.
