Some aspects of the revitalization of the 14th century historical building are presented in the paper. The building was originally used as a poorhouse and a hospital for children. The original Gothic masonry building on the site was a two-storey building with a cellar, situated in a corner of two streets. In the middle of the 19th century the building was converted into a school and then the first large-scale demolition of the hospital’s Gothic walls took place. After the 2nd World War a school was also situated in the building, where it existed until the late nineties. The aim of the renovation process was to convert it into an exclusive office block. The design works were preceded by historical research and on-site investigations. Complex conversion of the object consisted in the reconstruction of the old building structure, creating the inner courtyard and covering it with a glass roof. In the existing part of the basement one of the longest single-nave vaults in Poland and the exquisite roof truss system with a lying bidding-rafter post deserved special attention during the renovation.

Control Methodology

This paper presents active control design methodologies for control of tall building structures subjected to earthquake and wind disturbances. In particular, a robust control methodology based on passivity-based design techniques is given and is compared with traditional optimal control design methods such as LQR and LQG. The controller designs are tested in simulation on a multi-storied building structure subjected to an earthquake disturbance using the actual seismic data from the famous 1940 El Centro earthquake of the Imperial Valley in southern California. The comparison of open- and closed-loop responses show the effectiveness of passivity-based control design over LQR and LQG designs.

Modern construction techniques and good architectural views of building come with the concept of floating column. FC gives good architectural views to the structure also for the space requirement for parking or movements of vehicles floating column is delivered at the ground floor. Two models of six storey building structure with FC and structure with regular columns for the comparative study on the parameters such as flat displacement, storey drift, time period and base shear. RSA has been completed using ETABS 2016 software.

In this study, the problem of vibration control of structures involving parameter uncertainties and actuator saturation using hedge-algebras-based fuzzy controller (HAC) is presented. When structural damping and stiffness cannot always be measured easily and precisely, their uncertainties are assumed to be norm-bounded. The proposed controller is designed based on hedge algebras theory, where inherent order relationships between linguistic values of each linguistic variable, determined by isomorphisms mapping called semantically quantifying mapping based on few fuzziness parameters of each linguistic variable instead of using any fuzzy sets, are always ensured. The performance of the proposed controller is investigated by numerical simulations on active control of a benchmark three-storey building structure with active bracing system subjected to excitation of typical earthquakes. A conventional fuzzy controller, designed based on parameters similar to those of HAC, is also considered for the purpose of comparing effectiveness between controllers in order to shown advantages of the proposed method.
