In this way, it was verified that the project adopted for strengthening of the structure was not adequate to support the evolution of the maximum load over time and the overload due to widening, and it was also verified that the changes in the load factor do not comply with the update of the Brazilian Technical Standards ABNT: NBR-7188 [1]. The retro-analysis of the bridge rehabilitation project has demonstrated fundamental importance to avoid possible design failings, accidents, and reworks. Affirming that it is essential to comply with Standards and Technical Manuals on the elaboration of the rehabilitation project of structures and in choosing the type of intervention to the existing structure.展开更多

Since the publishing of Altman's (1968) major work, based on multiple discriminant analysis (MDA), this methodological area has considerably changed. Taking into consideration that new data have appeared in the course of time, companies' average size has changed, and the accounting standards have changed (Altman, Haldeman, & Narayanan, 1977), methods and models should be renewed so as to be appropriate for current situation. The purpose of this paper1 is to reveal factors causing bankruptcy and use models appropriate for prediction bankruptcy in the area of a construction industry during the financial crisis. This investigation has been carried out on the basis of logit and probit analysis. The main reasons of bankruptcy revealed in the course of this investigation are the following: (1) non-optimal capital structure formation; (2) ineffective liquidity management; (3) decrease in assets profitability; and (4) decrease in short-term assets turnover. The most reliable indicators which give warning of bankruptcy ahead of others are financial instability and liquidity ratios.展开更多
