structure to safeguard it from flooding or other risks such as high winds and earthquakes is known as retrofit. You've already seen examples of these changes, and you'll learn more about them in the future chapters. However, you may be wondering why retrofitting is so important. Building structures can be damaged for a variety of reasons, including earthquakes, cyclones, explosions, and so on. This type of loading causes the shape to pre-collapse or causes substantial damage to it. The structure can be retrofitted in the event of minor damage. A search of the existing literature indicated that there are numerous retrofitting approaches. The investigation is being conducted for the behaviour of ground floor R.C frame G+2 buildings. Assumed 3 m floor height. In addition, the attributes of the frame structure are defined. ETABS software is used to make models. Different types of loads are taken into account. For static behaviour, the building's dead load per IS 875 Part 1 and live load per IS 875 Part III are taken into account.
Concrete with longitudinal and transverse reinforcement is used to make the cladding for the columns. An improvement in electrical conductivity is achieved through this form of strengthening without affecting the column's bending strength or beam-column connections. Sheathing columns has also been proven to be ineffective at increasing ductility. Column sheathing's key benefit is that it improves the structure's lateral load capacity in a fairly even and dispersed manner, which diverts attention away from stiffness. This avoids the need for major foundational strengthening. In addition, because this technology does not fundamentally alter the unique geometry of the building, the actual function of the structure can be kept.

•
Existing structures, whether damaged or not, can be seismically strengthened through a process known as "retrofit."
•
Building assessments demonstrate that a restoration alone will not be sufficient to withstand future shocks if the original strength of the walls is found to be insufficient.
•
Retrofitting is the process of improving an existing structure's seismic resistance, ground movement resistance, or ground failure resistance.
•
Increases in the structure's lateral stiffness and ductility, with greater gradation.
•
Retrofitting rather than tearing down and rebuilding a structure is a more cost-effective and time-saving option.

1. INTRODUCTION An existing structure can be retrofitted to protect it from floods and other risks like high winds and earthquakes by making alterations to it. A number of these modifications will be introduced in the coming chapters. However, you may be wondering why retrofitting is so important in the first instance. Why aren't homes and other structures created in a way that they don't need to be altered? For one thing, advancements in construction technology, as well as our understanding of risks and their effects on dwellings, are continuously occurring. Houses built decades ago, when nothing was known about where and how often floods will occur, or how to protect them, can benefit from upgrades based on what we learn today.
