Our Construction System

In Turkey, the prefabrication was initiated in the 1960s. It is preferred especially in industrial buildings due to the reasons such as easy installation and manufacturing in a short time. However, the severe damages that occurred in prefabricated buildings in the recent devastating earthquakes required the development of new joint details for such building systems. Behaviour of buildings under the influence of seismic loads is affected by strength, stability and load-distributing features of joint details. When the causes for damage and destruction of the prefabricated buildings were investigated after the earthquake, it was found out that the majority of these buildings demonstrated poor performance due to insufficient lateral stiffness, cutting capacity and diaphragm movement, quality-control failure and incorrect details in the connection areas. For determination of seismic safety of the prefabricated building system, it should be experimentally and theoretically indicated that the joint zones have ductility and strength similar to the monolithic structural behaviour under the reversible-cyclic load that may occur during an earthquake. For this purpose, EMEK PREFABRIK implements FIX CAST – Industrial and FIX CAST – Residential building technique, which provides seismic safety with high production technology for industrial and residential buildings as a collaborative work of Emek Prefabrik project unit and academicians at universities by using its experience of producing safe buildings, which has been gained over the years and considering the experimental and theoretical data obtained within the scope of the EU-FR7:SAFECAST project as a joint work of Turkey Precast Concrete Association, of which the company is a member, and ITU university.
