Description

Strengthening and increasing the capacity of load-bearing walls of buildings after an earthquake is a challenge that requires special study. A viable option is strengthening using standard cement-based materials.
This paper will first present and discuss the buildings with load-bearing walls that have shown earthquake survival ability, as well as some methods to improve their performance.
The example that is used for discussion is a building that has suffered significant damage from the 2019 earthquake in Albania. The paper will present the calculation of the performance and capacity of this building with the load-bearing walls made of clay and silicate bricks after an earthquake of magnitude M=6.2 Richter. The building comprises load-bearing walls and was built in the 60s-70s. The materials characteristics used in calculations are derived from laboratory tests and on-site non-destructive testing. The results obtained from the calculation of the building before and after the earthquake and after the reinforcing of the building will be compared. The strengthening of walls is made using cement-based materials. The calculations are performed using SAP2000 and ETABS software and include static and dynamic performance.
The results of the calculations will be analyzed to conclude the effectiveness of the rehabilitation of the buildings. The environmental and socio-economic impacts on society from the strengthening of buildings damaged by earthquakes will also be presented.
