Designing Of Curricula Of Environmental Engineering And Constructions Engineering For Sustainability

The experience carried out at the University of Florence, Department of Civil and Environmental Engineering, in designing two new undergraduate curricula in “Environmental Engineering” and “Civil and Building Engineering for sustainability”, is reported. The bachelor in Environmental Engineering aims to train engineers capable of working in the field of protection of environment, territory and natural resources. The bachelor in Civil and Building Engineering for sustainability aims to train engineers capable of working in the field of structures, infrastructures, and constructions in general, as well as management and safety of construction processes. The development of the two curricula was based preliminarily on a national and international survey of degree programs of the same type and with shared learning outcomes. Subsequently, labour market needs were identified starting from discussions with all stakeholders, students and professors included. Teaching methods and methods for assessing students\u27 preparation have also been revised and the teaching plan of both curricula is characterized in the third year by the presence of multidisciplinary laboratories, focused on the most characterizing themes of each programme and the different disciplines with integrative and specific in-depth characteristics. Finally, a thorough design of the two courses contents has been initiated, based on the definition of the general educational objectives and the specific disciplines

Correction of Mechanical CPT Data for Liquefaction Resistance Evaluation

Abstract -For more than 30 years, there has been considerable interest in using CPT also to evaluate the liquefaction resistance of soils. Unfortunately, most of the simplified methods used for liquefaction resistance evaluation only require in situ measurements from electrical cone penetrometers even if they are frequently applied using measurements from mechanical CPTs that are still preferred by current engineering practice in many countries. Erroneous estimates of liquefaction resistance and relevant non-conservative results are obtained by applying electrical CPT-based methods to mechanical CPT data without any form of correction. This study focuses on the developing of an appropriate procedure for correcting mechanical CPT data and provides modified equations for liquefaction resistance estimation by means of electrical CPT-based simplified methods. A dataset of more than 3900 pairs of measurements of cone tip resistance and sleeve friction were obtained from 44 sites selected in Northern and Central Italy and processed by means of statistical analyses. Suitable adjustments to CPT mechanical data were proposed for determining corrected liquefaction potential
