Seismic retrofit of existing building with soft ground storey: a case study with different strengthening solutions
The current example employs a typical building built in the late 1980s. The building has 5 floors of approximately 180 m2 each, and a soft storey at the ground level. The infills of the upper levels are relatively strong with good quality ceramic bricks and mortar of relatively high strength. The combination of the soft ground storey and strong infill panels in upper floors is the most important characteristic of the building and constitutes a serious structural problem related to its seismic behaviour.
Seismic retrofit of an existing industrial building with short columns: a case study with different strengthening solutions
The current example employs a typical industrial building built in the late 1980s. The building has 2 floors of approximately 880m2 each. The infills are relatively strong with good quality ceramic bricks and mortar of relatively high strength.
A Seismic Retrofit case study with different strengthening solutions
The recent Turkey - Syria earthquake inspired us to write a blog post about the importance of seismic retrofit of existing buildings. The current example - case study - employs a typical building built in Southern Europe in the late 1980s. The building has 4 floors of approximately 200 m2 each, and a soft storey at the ground level.
Major Earthquakes hit Southern Turkey
SeismoSoft team passed the largest of the recordings to SeismoSignal and the findings were astonishing.
Steel Bracing
Steel bracing offers similar advantages to new shear walls, increasing the strength, the stiffness and the ductility of the building.
New Reinforced Concrete Shear Walls
This method consists of the construction of new shear walls with large dimensions at selected locations in the building perimeter and/or in the interior of the building.
Seismic Isolation
This post aims to present main aspects of seismic isolation in the strengthening of a reinforced concrete building, the available types of base isolation, as well as their advantages and disadvantages.
