Abstract

Neer mahal palace is one of the pioneering structures built by Royal family of Tripura, India in the midst of a Lake named Rudrasagar. It is a structure which attracts lots of tourist in this north eastern remote state of India. Being a masonry structure and situated in a Earthquake prone area (Zone V), it is under threat of possible damage. This paper aims to evaluate the actual structural condition of the Neer mahal palace using some Non Destructive test, like Corrosion analyzer and concrete test hammer, along with finding potential vulnerable zone of the palace under seismic condition using numerical model. The result shows that in the majority of cases chance of corrosion occurrence in the slab of concrete is less than 10% and in some cases it is uncertain. It also shows that the quality of concrete in maximum places is in good condition and in few cases it is under fair condition. Masonry Sub structure of the palace shows significant loss of strength. Seismic analysis results reveal that the structure is not under a serious stability threat, and maximum stress occurred in ‘Durbar hall’ area. The response spectra analysis result shows that maximum displacement values is 36.40mm which occurs with maximum expected ground acceleration of 0.32g.
