摘要：

India has long been admired for its architecture that is an amazing confluence of knowledge, art and fine craftsmanship. As one of the oldest and most diverse civilizations of the world, one can find stunning temples, forts, palaces and monuments made in wood, across the length and breadth of
the country. Being naturally occurring material, construction using it was the order of the day for centuries till the other materials began to gain popularity.47Rajwada, is a historical Residential palace in the city of Indore, Madhya Pradesh, Central India. This seven storied palace serves as a fine example of royal grandeur of Holkars of the Maratha Empire. It was built in 1766 and later the southern part was rebuilt in the years 1811–1833 after being damaged by fire. The palace faced maximum destruction during 1984 riots. The lower three stories of the palace are constructed with stone while the upper four floors are made of wood and thus they are more prone to fire.
A team of Architects, Civil Engineers and Wood Scientists were given the task to rebuild this building using the same material & finishes, while adhering to the seismic structural requirements, mandatory today. Forest Research Institute, Dehradun was approached for consultancy on wood, and thus the authors carried out the study.
The upper three Wooden floors of the Palace were found to be facing major problem of Outside Tilting, Open Joints of columns and beams, Longitudinal fractures at places with bigger nails, Centre Sagging of beams, Borer and termite attack and Bio deterioration of wood.
The woods used in Rajwada palace were examined through both random and selective sampling method. Over 100 samples were examined on site and 8 wood samples were brought for lab testing. Over 95% of the wood used in the Palace is Teak (Tectona grandis). Besides Teak, Hardwickia binata (Anjan), Anogeissus acuminata (Yon) and Pterocarpus marsupium (Bijasal) were used at different places. The highly deteriorated woods of the beams at third floor were of miscellaneous wood species. The presentation shall deal with the choice of different woods for different purposes and the probable reasons for failure of the wooden structure.
