- Description
- The study of the evolution of Italian anti-seismic legislation reveals the strategies and means of operating that have influenced and characterized the restoration of historical
buildings in Italy. This work looks at some of the most important steps in anti-seismic legislation from the unification of Italy to the present day, with the aim of highlighting how legislation reflects the technical culture of differing periods, influencing the work practices involved in the restoration of the historical building patrimony, and how legislation has slowly changed to incorporate a growing interest in the safeguarding and conservation of the historical and architectonic patrimony. Safety legislation, in fact has often led to the incorporation of invasive structural
elements that are out of place with respect to the original building tissue. In the first half of the last century, the impossibility of applying the models of modern science to
stone buildings led to the transformation into frame-schemes through the insertion of new resistant structures. The 1908 Norms amended over time then led to the passing
of Law 64/74. The Law and decrees that followed have focused on new construction and only marginally on the problems linked to work on existing structures although the most recent decrees issued by the Ministry of Public Works have shown a growing awareness of this theme which is gaining more interest on a cultural and scientific level, introducing the concept of “upgrading” as an alternative to “anti-seismic retrofitting” and as natural means of acting on monumental buildings. The most recent legislation includes the Ordinance of the President of the Council of Ministers n° 3274/03 and its amendments, and “Technical norms for construction” (Decree of the Ministry of Infra-structure and Transport n° 159 dated 14/9/2005), updated with the Decree of the Ministry of Infra-structure dated 14/11/2008.

- Design of building structures to improve their resistance to progressive collapse

- Description
- It is rare nowadays for a “new topic” to emerge within the relatively mature field of Structural Engineering. Progressive collapse – or, more particularly, understanding the mechanics of the phenomenon and developing suitable ways to accommodate its consideration within our normal frameworks for structural design – can be so regarded. Beginning with illustrations drawn from around the world over several decades and culminating in the highly public WTC collapses, those features essential for a representative treatment are identified and early design approaches are reviewed. More recent work is then reported, concentrating on developments of the past seven years at Imperial College London, where a comprehensive approach capable of being implemented on a variety of levels and suitable for direct use by designers has been under development. Illustrative results are used to assist in identifying some of the key governing features, to show how quantitative comparisons between different arrangements may now be made and to illustrate the inappropriateness of some previous design concepts as a way of directly improving resistance to progressive collapse.

- Very large floating structures: Applications, research and development

- Description
- Very large floating structures (VLFS) have attracted the attention of architects, city planners, and engineers because they provide an exciting and environmentally friendly solution for land creation from the sea as opposed to the traditional land reclamation method. The applications of VLFS as floating piers, floating hotels, floating fuel storage facilities, floating stadia, floating bridges, floating airports, and even floating cities have triggered extensive research studies in the past two decades. The VLFS technology has developed considerably and there are many innovative methods proposed to minimize the hydroelastic motion, improve the mooring system and structural integrity of the VLFS. This keynote paper summarizes the applications, research and development of VLFS over the past two decades.

- Evaluating the Value of Early Planning for Building Information Modeling Using Lean Theory

- Description
- Building Information Modeling (BIM) provides a means for owners, designers, contractors, and operators to generate, organize and use detailed information throughout a project lifecycle. An important aspect to the success of BIM is the process in which information is exchanged between project team members. In theory, information should be both accessible and usable, when required. Because the AEC industry is project centered, and several companies work collectively towards the design and construction of a facility, the availability and accuracy of information can become constrained. Building Information Modeling has the potential to improve efficiency in the AEC industry; however, if the information exchange (IE) process is not planned early in the project lifecycle, the benefits of using the authored data may be mitigated by process waste.
This paper serves to evaluate the value of early team planning as it pertains to performing BIM tasks in the construction phase of a project. The rationale behind lean theory is to increase efficiency by eliminating waste, consequently increasing value. To illustrate the value of early project planning for BIM, this research focuses on the information exchange waste produced on a case study project. During the case study process actual information exchanges were evaluated using the seven types of waste: overproduction, inventory, extra processing, motivation, defects, waiting, and transportation. Finally, time and resources were allocated to each
non-value added aspect of information exchange through interviews with the project team members. This procedure produces a total cost of IE waste which was then correlated to the lack of early planning. Using this methodology, the Millennium Science Center (MSC) project on the Pennsylvania State University campus was evaluated to determine the economic benefit associated with the early planning of BIM on future projects.

- Using Construction Deficiency Reports and Product Models as Systematic Feedback to Avoid Design Errors Caused by Lack of Knowledge

- Description
- Design errors cause a big part of the defects occurring in building production and maintenance. Earlier research have shown that the most common cause for design errors is lack of knowledge. Product-model based CAD-systems are increasingly used in structural engineering practice and it is well known that these systems reduce the design errors, mostly through better visualization and collision checks. The design errors caused by lack of knowledge are not prevented using product-model based CAD-systems as we do today. This paper describes a case study of design errors where the structural engineer is involved. The aim of the study was to find new ways to prevent design errors using the product-model based technique. The study supports earlier findings that the use of product-model based CAD-systems have a great potential in preventing design errors, especially co-ordination errors. The study also shows that many of the design errors caused by lack of knowledge could be prevented in future projects if the design errors from earlier projects were systematically documented and made available to the structural engineer in the design process. This could prevent as many design errors as is prevented by using product-model based CAD-systems today. The study shows that about 90% of the design errors that could be prevented in this way were situated where two or more elements meet. It was also found in the study that the information needed about the design errors could be retrieved from construction deficiency reports. Based on these findings it is argued that design errors, caused by lack of knowledge, can be prevented in future projects by making the information from the construction deficiency reports available and retrievable for the structural engineer by indexing them using information about the elements meeting where the design error occurred.
