Structural Evaluation of Tall Buildings Using Ferroconcrete and Steel-Timber Hybrid Systems under Lateral Loads in ETABS

In a densely populated and rapidly urbanizing country like India, the construction of multistorey buildings is
essential to meet increasing housing and infrastructure demands. These structures are often subjected to lateral forces, which
act horizontally and can significantly affect their performance. Such forces primarily include wind loads and seismic activity,
both of which can cause structural deflection, instability, or even failure if not adequately addressed. To ensure buildings can
withstand these lateral effects, advanced structural analysis tools like ETABS are employed. ETABS is a comprehensive
software used for modeling, analysis, and design of buildings in compliance with national and international codes. It provides
accurate simulations of how structures respond to various loading conditions, making it ideal for evaluating complex buildings.
Hybrid structural systems, which combine different construction materials, are gaining popularity for enhancing structural
performance. One common and effective hybrid combination is steel and concrete, which leverages the tensile strength of steel
and the compressive strength of concrete. Steel is especially favoured for its high load-carrying capacity and fast construction
capabilities, and when integrated with other materials such as timber or ferrocement, it helps overcome limitations inherent to
individual materials. This study investigates a G+7 storey steel-timber hybrid building reinforced with ferroconcrete (wire
mesh embedded in concrete). A three-dimensional static analysis is performed using ETABS to assess the building’s structural
behavior. The study focuses on key parameters such as maximum nodal displacement, bending moment, shear force, axial
force, and storey drift to evaluate the effectiveness of the hybrid system under lateral loading conditions
