The Ayodhya Ram temple, which has attracted a large number of devotees, is designed to withstand the largest earthquake that occurs once in 2,500 years.

CSIR-Central Building Research Institute (CSIR-CBRI) – Roorkee carried out a series of scientific studies of the Ayodhya site including geophysical characterization, geotechnical analysis, foundation design investigation and 3D structural analysis and design .

“The scientific study was carried out to ensure the structural safety of the temple during the considered maximum earthquake, equivalent to a return period of 2,500 years,” Debdutta Ghosh, senior scientist at CSIR-CBRI, told PTI.

Ghosh and Manojit Samanta, coordinators of the Center of Excellence for Conservation of Heritage Structures at CSIR-CBRI, led the teams in reviewing the design and monitoring of the foundation, and carried out 3D structural analysis and design of the Ram mandir.

The couple was guided by CSIR-CBRI director Pradeep Kumar Ramancharla and his predecessor N Gopalakrishnan.

Ghosh said the geophysical characterization process involved multichannel analysis of surface waves (MASW) to estimate the primary wave velocity, along with electrical resistance tomography to identify anomalies, water saturation zones and water table levels.

These findings served as crucial inputs for a site-specific response for underground investigations and estimation of seismic design parameters, he said.

The CSIR-CBRI also examined soil investigation schemes, foundation design parameters, excavation schemes and recommendations for monitoring of foundations and structures.

Ghosh said the structural design was recommended after simulating over 50 computer models and analyzing them under different loading conditions to determine their optimal performance, architectural attractiveness and safety.

The entire superstructure was constructed of Bansi Paharpur sandstone, representing a dry bond structure without steel reinforcement, designed for a service life of 1,000 years, he said.

The superstructure material, Bansi Paharpur sandstone, has been tested at the Center to evaluate the engineering properties which were used as input for the structural analysis.

Specialized brick with a compressive strength of more than 20 MPa (mega pascals), or approximately 2,900 pounds per square inch (psi), has been used in the structures at 28 days of curing under standard conditions, Ghosh said.
