Seismic Evaluation of Existing Structures

Retrofit

Seismic evaluation of existing buildings using linear and nonlinear analysis is a sophisticated method for assessing structural performance under earthquake loading. Linear analysis assumes elastic behavior of materials and is suitable for preliminary evaluation. Nonlinear analysis considers more realistic behavior, including yielding and permanent deformations, and is used for detailed vulnerability assessment and determining the need for retrofit. These analyses form the foundation for decision-making in seismic rehabilitation.

Seismic Retrofit Design Services

Our seismic retrofit design services include vulnerability assessment of existing buildings using both linear and nonlinear analysis, determining target performance levels, and selecting appropriate retrofit strategies. During this process, structural deficiencies are identified, and solutions such as shear walls, bracings, concrete or steel jacketing, and FRP strengthening are proposed. The retrofit scheme is then developed through numerical modeling and design to produce a detailed implementation plan. The goal is to enhance seismic safety and ensure compliance with building code requirements.

Seismic Assessment of Steel Structures

Seismic assessment of steel structures involves evaluating their behavior and performance under earthquake loading. This includes reviewing strength, ductility, connection details, and overall dynamic response. Using advanced analysis software and recognized standards, structural weaknesses are identified and retrofit strategies are proposed. The primary objective of this process is to enhance life safety and minimize structural and economic losses during seismic events.

Seismic Assessment of Reinforced Concrete Structures

This assessment focuses on evaluating the strength, stiffness, and ductility of reinforced concrete members under seismic loads. It involves code-based structural analysis, assessment of columns, beams, and connections, and identification of potential weak points. Through numerical techniques and non-destructive testing methods, the structure’s behavior under earthquake loading is examined, and retrofit solutions are developed. The aim is to improve structural safety, minimize damage, and optimize seismic performance.
