Abstract
Adding greenhouse structures to existing residential structures in order to increase agricultural products is considered as a challenge. In this paper the comparison of a three-dimensional residential building is investigated in three cases: without greenhouse structure, with rigid connection to the greenhouse structure and the greenhouse structure seismically isolated from the base structure using FPS. It was observed that adding additional mass on the last floor of the base structure can cause an unpredictable increase in the amounts of base shear and roof displacement. It was observed that FPS showed a proper behavior during near-field earthquakes. In terms of base shear and roof displacement the structure with FPS showed a better performance than the structure without FPS.
Highlights
Due to the massive increase in the world population during the past recent centuries, the importance of providing enough agricultural products is undeniable to human beings
In terms of base shear and roof displacement the results show an erratic and unpredictable behavior of the structure before and after adding the greenhouse structure
The additional mass on the last floor of the considered structure had an erratic effect on the base structure
Summary
Due to the massive increase in the world population during the past recent centuries, the importance of providing enough agricultural products is undeniable to human beings. The distance between where the agricultural products are made and where these products will be consumed can cause expensive distribution costs and in some cases the products will lose their adequate quality because of the time wasted for transportation. This problem could get significantly improved if the locations that products are made and used were in the cities. The idea of adding greenhouse structures to the existing buildings is not a new concept It seems that the effect of this extra mass to the base structure during an earthquake is neglected. Near-field earthquakes have rich frequency contents and despite the far-field earthquakes higher frequencies exist in the records (Ghobarah, 2004)
