The Ontario Highway Bridge Design Code (OHBDC) introduced in 1979 a new set of provisions for the design of soil–steel bridges. Some of these provisions have been revised in the third edition of OHBDC (1991) to reflect the outcome of research that has been conducted since. This paper presents details of these revisions and provides the reasons for their inclusion. In particular, a new method of calculating dead load thrust and improvement to the buckling analysis of the conduit wall are discussed. Key words: buckling, pipe-arch, soil–steel structure, thrust.

Current steel structure design software cannot calculate sectional properties of user-defined section of cold-formed thin-wall steel accurately. Since the sectional properties data given by design code has been implanted into corresponding modules of these software and the software disregard the radian of corner of steel, erroneous results will be generated if the user-defined sectional size doesn't match the sectional size of the data file implanted. According to Green's theorem, the author derived precise formulas for sectional properties of arbitrary section and developed software for calculation based on Visual C++ platform. The software which can calculate exact solution of sectional properties of arbitrary section has been verified by comparing results from various methods. This software can be used independently as a calculating tool and the calculation module can be implanted into other steel structure design software to make calculation for sectional properties of arbitrary section possible.

The Maari DrillACE Well Head Platform (WHP) was installed offshore New Zealand during the second quarter of 2008 for the designated operator OMV New Zealand Ltd. The platform was engineered and designed by Arup and Clough. Clough was responsible for engineering, procurement, construction and installation activities on the project, with Arup undertaking the design of the primary steel structure, including the plated base, deck and tubular jacket. The Maari WHP was the third ACE platform and the second DrillACE platform to be installed. This paper considers a number of the unique features of the structural design of the Maari DrillACE platform that were encountered during this project as well as providing a background on the ACE platform concept.

Response Spectrum Analysis

Considering the structure type of the steel staggered-truss (SST) system, the effect of infilled walls will be major and need to be studied amply, some scientific design regulations need to be found for referrence. Based on two different 3D models considering or ignoring the stiffness of infilled walls (SIW), a numerical investigation is presented on the structural behaviors of the SST system utilizing the finite element 3D simulation analysis soft ware ETABS. The longitudinal structure is asymmetrical due to the SIW, it causes the torsion forces in the building. Comparing to the different results of response spectrum analysis, including storey drift and equivalent base shear under frequent earth quake and rare earth quake, some conclusions were made, including the capacity of the SST system under seismic load and the effect of the SIW for SST system. The increased base shear force factors due to the effect of the SIW were suggested for SST structure design, it is different from the other steel structure types.

The 3D visualization design of steel structure under the CAD environment needs to work in the global coordinate system (WCS), but design of various steel members in the 3D space must be completed in the local coordinate system (UCS), so it is perplexing for the conversion and calculation between UCSi (i=1,2,3....n) and WCS. It is proved that the maize grains are not polluted and food production is in safe condition. The article describes classification of several common coordinate systems, discuss the method of setting up coordinates system. Describe the process of type convertion of coordinate system in steel structure design and detailing softwares, and explained the advantage of the application in the real world project.
