Abstract:-The objective of this study is to assess the seismic
occurred and disaster has taken place; how to use the debris to construct economical houses using this waste material without affecting their structural stability. Rapid visual screening of buildings for potential seismic hazards, as described here in, originated in 1988 with the publication of the FEMA 154 report.This FEMA 154 hand book is used all over word as a reference, But some of the parameters are not visualize for Indian condition, Making a new form of RVS.
vulnerability of R.C.C. and load bearing structure of the Chiplun City area by R.V.S (Rapid Visual Screening) method for Indian condition. The RVS method is a preliminary survey conducted to check the seismic vulnerability of existing structures in a systematic way. The method consists of the steps as, visual inspection followed by detailed investigation and finding a score which decides the need of detail seismic structural analysis. An attempt has been made to do rapid visual screening of RCC building and Load bearing building which available in Chiplun. RVS score has calculated for 40 buildings and plotted normal distribution Graph for each building to understand the distribution of RVS score of buildings in Chiplun. From the study, Results of the performance scores more than 2 around 57% (23 out of 40) of buildings are reinforced concrete as well as Load bearing structure also, Results of the performance scores more less than 2 around 43% (17 out of 40) of buildings are reinforced concrete as well as Load bearing structure. However, there are some low RVS score buildings which are potentially vulnerable to future earthquakes. Also it is suggested that preliminary analysis needs to be performed detailed analysis for 17 buildings for calibrating RVS scores.
II STUDY AREA The town lies on the banks of the River Vashishti which flows up to Gowalkot, a village 2.5 km from Chiplun to the east of the city lay the Western Ghats and to the west lays Guhagar. The region has a tropical climate.
Key Words: - Survey, Skill, Rapid visual screening, RVS forms for load bearing and RCC structure
1. INTRODUCTION
Fig 1 Map of Chiplun City Hard Strata found up to 10 TO 15 Feet down and the water table is up to 35 TO 40 Feet below the ground level. (According to municipal data)
The all humans are totally depends on the activity of earth. Some of activity are helpful some of the very danger to human life. For example three season summer, winter and rainy season are essential to human. In other hand volcano, tsunami, cyclone, greenhouse effect and earthquake are such most danger activity on our planet. Whereas the volcano, tsunami, cyclone are predicted before activity, so we can reduce the losses. But earthquake is most complicated and unpredictable activity on the earth.
For that survey we select Chiplun city because of this city is very close to the Koyana Hydroelectric Project and this location is also high seismic zone which affect the Chiplun city after some year. Already Chiplun is in IV zone of seismicity so before earthquake occurs we have to ready for minimize the damages for structure and human life as well as economy also.
We know that no any structure in the earth is totally earthquake resistance. But we can minimize the losses for earthquake by taking some precautions. India faces serious earthquake problems by a rapid growth of urban population. Nearly 60% of landmass in India is under moderate to severe earthquake prone area. During 2001 Bhuj preliminary assessment, and (c) detailed evaluation. Rapid visual screening (RVS) not only this, once the earthquake has

Chiplun is very old city so that there having more old structure in which include old wooden structures, steel with wooden structure, load bearing laterite structure and R.C.C. frame structures etc. Market area in the city is more crowded. This area having more than 500 shops (large and small), also in this market include Hospitals, Schools and
