Abstract:

As an alternative to lap splicing, mechanical splices can be used for retrofit purposes. They are generally most economical than traditional lap splices when available spacing or length makes laps difficult to utilize. Mechanical splices are frequently used in new construction. However, their use is limited and not practical for use in retrofitted structures. However, if the bars to be joined do not need to be threaded in order to be connected with a special mechanical splice, such mechanical splices can be useful. It is presented a proposal of using two types of mechanical splices for retrofi

Abstract:

Many buildings constructed during the middle of the 20th century were constructed with criteria that fall short of current requirements. Although shortcomings are possible in all aspects of the design, the inadequacies in terms of seismic design present a more pressing issue to human life. This risk has been seen in various earthquakes that have struck Italy recently, and subsequently, the codes have been altered to account for this underestimated danger. Structures built after these changes remain at risk and must be retrofitted depending on their use. This report centers around the Giovanni

The effectiveness of seismic retrofitting applied to enhance seismic performance was assessed for a five-story reinforced concrete (RC) flat-slab building structure in the central United States.

The response of the structure was predicted using nonlinear static and dynamic analyses with synthetic ground motion records for the central U.S. region. In addition, two analytical approaches for nonlinear response analysis were compared. FE

Abstract:

When the huge building stock in Turkey is considered, it is practically impossible to carry out detailed structural analyses for all of the buildings. In order to cope with the seismic safety evaluation of a large number of existing buildings, it is necessary to use simplified techniques, which can predict the seismic vulnerability of the existing buildings in a relatively short time. The comprehensive structural data compiled for the 48 different reinforced concrete buildings contain full information on their structural characteristics before and after retrofitting and are used in this study.

Additionally, the increased duration of a CSZ earthquake may result in more structural damage than expected.

Dissertação de mestrado em Structural Analysis of Monuments and Historical Constructions<br>Anthropological reasons apart, earthquakes are one of the most devastating causes of damage to monuments and historical constructions, and, as a consequence, lead to significant cultural, human, and economical losses. Protection of such structures against seismic excitations is thus an important factor regarding life safety and the conservation of our historical heritage. Efficient connections between structural elements can highly reduce the seismic vulnerability of masonry buildings by enhancing

Abstract:

The main purpose of the present dissertation is to study the efficiency of buckling restrained braces (BRB) when used as seismic dampers in reinforced concrete frame structures. The study was conducted on the RC frame structure reported by Sarno and Manfredi. Their experimental campaign results, available for the structure with and without BRBs, were used to calibrate a numerical model implemented in the FE program SeismoStruct. A probabilistic approach was used next to assess the efficiency of the BRBs. Following the provisions of the Probabilistic Model Code of the Joint Committe of

Majority of building collapse resulted from the loss of vertical-load carrying capacities of columns. Most of the damaged columns were found with non-ductile detailing, such as widely spaced hoops with 90 degree hooks. Such columns are known to have poor seismic performance in terms of ductility and energy dissipation capacity. Five reinforced concrete frames with bric

Masonry walls provide a certain amount of lateral strength for the structure when an earthquake occur, so Masonry walls are also an important seismic structural component. The lateral strength of the Masonry wall is related to the fracture path. The previous proposed two methods to reinforce the Masonry wall: Carbon Fiber Reinforced Plastic Sheet and Pre-tensioned Rods,in order to change the failure path of the wall and

Abstract:

Soft-floor buildings, characterized by open spaces on the first floor, pose challenges to seismic performance. To address this, braces and shear walls are commonly employed to reduce displacement and improve seismic resilience. Shear walls and braces enhance lateral stiffness, minimize displacement, and ensure safety. This study investigates the seismic response of soft-floor RCC buildings, considering parameters such as soft floor height, shear wall placement, and brace types and arrangements. The goal is to enhance structural safety without extensive alterations. Analysis is
