An application of reliability-based robustness assessment of steel moment resis...

The paper presented herein proposes a reliability-based framework for quantifying the structural robustness considering the occurrence of a major earthquake (mainshock) and subsequent cascading hazard events, such as aftershocks that are triggered by the mainshock. These events can significantly increase the probability of failure of buildings, especially for structures that are damaged during the mainshock. Th...

A framework for robustness assessment in the context of corroded RC structures

Structural robustness is an emergent concept related to the structural response to damage. At the present time, robustness is not well defined and much controversy still remains around this subject. Even if robustness has seen growing interest as a consequence of catastrophic consequences due to extreme events, the fact is that the concept can also be very useful when considered on more probable exposure scenar...

Probabilistic models for mechanical properties of prestressing strands

This study focus on the probabilistic modelling of mechanical properties of prestressing strands based on data collected from tensile tests carried out in Laboratório Nacional de Engenharia Civil (LNEC), Portugal, for certification purposes, and covers a period of about 9 years of production. The strands studied were produced by six manufacturers from four countries, namely Portugal, Spain, Italy and Thailand. ...

Object-oriented graphics software for multimedia applications

This paper describes the development of a highlevel integrated environment for PCs with graphics programming support.The development was carried out on the WindowsTM environment, with C++ language and multimedia tools. The result of this development was the creation of a graphic objects class with static and dynamic features and a graphic editor with graphic animation support (&ldq...

Working capital management and profitability: the Telecom case

Mestrado em Finanças ; The Working Capital Management should be carried out as efficiently as possible in order to maximize value creation for the various stakeholders. This relationship between efficiency and profitability has been examined by several authors who have attempted to establish this relationship through the analysis of three elements: current financial management policies, size and industry. The ...

Earthquakes and robustness

This guideline was prepared within the COST Action E55 "Modelling of the performance of timber structures" WG3 "Robustness of Structures". The main objective of the Action is to provide the basic framework and knowledge required for the efficient ans sustainable use of timber as a structural and building material. Focus is directed on the aspects of design, construction, assessment and maintenance of competitiv...

Robustness of timber structures in seismic areas

Major similarities between robustness assessment and seismic design exist, and significant information can be brought from seismic design to robustness design. As will be discussed, although some methods and limitations considered in seismic design can improve robustness, the capacity of the structure to sustain limited damage without disproportionate effects is significantly more complex. In fact, seismic desi...
