현재 우리나라에서는 지역의 산업경쟁력을 제고하기 위한 지역혁신체제를 구축함에 있어 핵심적 매개주체의 육성이 핵심적 과제가 되고 있다. 이에 본 연구는 선진 사례로서 이탈리아 에밀리아 로마냐 지역의 지역개발기구인 ERVET 시스템을 고찰함으로써 우리나라 지역혁신체제 구축에 있어서의 정책적 함의를 도출함을 목적으로 한다. ERVET 시스템은 지역경제발전을 위한 정책을 입안하고 시행할 뿐 아니라 해당 지역의 기업들이 필요로 하는 리얼 서비스를 직접 제공하는 수요자 중심적 활동을 하고 있다. 또한 대학$.$연구기관과 기업들을 네트워크 관계로 묶어냄으로써 이들 간에 필요로 하는 지식과 정보가 원활히 이전될 수 있도록 하는 소프트웨어 중심의 지역혁신체제를 구축해 왔다. ERVET 시스템에 대한 사례 연구를 토대로 하여, 필자들은 현재 우리나라의 지방정부는 타율적이고 위계적 관료주의 성향이 지배적인 실정에서 지역혁신정책을 효과적으로 수행하기 어렵다는 사실을 인식하고, 각 광역자치단체 별로 ERVET 시스템을 비롯한 선진 지역개발기구의 운영 사례를 벤치마킹하여 우리의 실정에 맞는 지역개발기구를 설립할 것을 제안한다.

Seismic assessment and rehabilitation of Monumental Buildings constitute an important issue in many regions around the world to preserve cultural heritage. On the contrary, many recent earthquakes have demonstrated the high vulnerability of this type of structures. The high nonlinear masonry behaviour requires ad hoc refined finite element numerical models, whose complexity and computational costs are generally unsuitable for practical applications. For these reasons, several authors proposed simplified numerical strategies to be used in engineering practice. However, most of these alternative methods are oversimplified being based on the assumption of in-plane behaviour of masonry walls. Moreover, they cannot be used for modelling the monumental structures for which the interaction between plane and out-plane behaviour governs the structural response. Recently, an innovative discrete-modelling approach for the simulation of both in-plane and out of-plane response of masonry structures was proposed and applied to study several typologies of historic structures. In this paper the latter model is applied with reference to a real case study, and numerically compared with an advanced finite element modelling. The method is applied to the St.Venerio church in Reggiolo (Italy), damaged during the 2012 Emilia-Romagna earthquake and numerically investigated in the literature.

Recent seismic events occurred in Italy (Emilia-Romagna 2012, Abruzzo 2009) and worldwide (New Zealand 2010 and 2011) highlighted some of the weaknesses of precast concrete industrial buildings, especially those related to the connecting systems traditionally employed to fasten the cladding panels to the internal framing. In fact, one of the most commons fails it is possible to observe in such structural typologies is related to the out-of-plane collapse of the external walls due to the unsatisfactory behaviour of the connectors used to join the panels to the perimeter beams. In this work, the strengthening of a traditional industrial building, assumed as a case study, made by precast reinforced concrete is proposed by the adoption of a dual system allowing the reinforcement of the structure by acting both internally; by pendular columns and, externally, on the walls. In particular, traditional connections at the top of the walls are substituted by devices able to work as a slider with vertical axis while, the bottom of the walls is equipped with two or more hysteretic dampers working on the uplift of the cladding panels occurring under seismic actions. By means of this approach, the structure is stiffened; obtaining a reduction of the lateral drifts under serviceability limit states. In addition, its seismic behaviour is improved due to the additional source of energy dissipation represented by the dampers located at the base of the walls. The effectiveness of the suggested retrofitting approach has been checked by comparing the performance of the retrofitted structure with those of the structure unreinforced by means of both pushover and Incremental Dynamic Analyses (IDA) in terms of behaviour factor, assumed as a measure of the ductility capacity of the structure.
