The main purpose of the present work is to investigate the impact of soil-structure interaction on performance-based design optimization of steel moment resisting frame (MRF) structures. To this end, the seismic performance of optimally designed MRFs with rigid supports is compared with that of the optimal designs with a flexible base in the context of performance-based design. Two efficient me...

The second release of the CIMsteel Integration Standards (CIS/2) has been endorsed by the American Institute of Steel Construction as the standard for the electronic exchange of structural steel project information for the North American steel design and construction industry. Derived from the deliverables and experiences of the Pan-European Eureka CIMsteel Project and published by the Steel Co...

This paper proposes a new approach to representing structural system inspired by various models of complex systems. Several types of generative representations of steel structural systems are provided and empirically investigated. These representations utilize various kinds of cellular automata to generate design concepts of steel structures in tall buildings. In the paper, a brief overview of ...

Concrete filled tube (CFT) columns have been used as primary axial load-carrying members in high-rise building especially in seismic zones. The structural member has become popular as it has a number of distinct advantages over an equivalent steel, reinforced concrete, or steel-reinforce concrete structural member. This paper is intended to presents numerical modeling of elliptical concrete-fil...

One of the main tasks of engineers is to design structural systems light and economic as possible, yet resistant enough to withstand all possible loads arising during their service life and to absorb the induced seismic energy in a controlled and predictable fashion. The traditional trial-and-error design approach is not capable to determine an economical design satisfying also the code require...

The stress in structural steel members is the most useful and directly measurable physical quantity to evaluate the structural safety in structural health monitoring, which is also an important index to evaluate the stress distribution and force condition of structures during structural construction and service phases. Thus, it is common to set stress as a measure in steel structural monitoring...

A review of the current situation and development of fire safety design for steel structures in China is given in this paper. Several codes and specifications used for fire safety design in China are introduced, and the present design methods are summarized. Then some research achievements on the behavior of steel structures at elevated temperature are presented. The achievements include materi...

Fiber-reinforced polymer (FRP) has been increasingly applied to steel structures for structural strengthening or crack repair, given its high strength-to-weight ratio and high stiffness-to-weight ratio. Cracks in steel structures are the dominant hidden threats to structural safety. However, it is difficult to monitor structural cracks under FRP coverage and there is little related research. In...

One of the most prohibiting factors when attempting to reuse structural steel members or systems of members is the time and labour required to accurately determine dimensions. Current practices dictate that all required measurements are recorded by hand using tape measures and calipers which adds a significant cost to reused steel. To mitigate this cost, a semi-automated method for identifying ...
