The sympathetic restoration and conservation of built cultural heritage play a significant role in the management and preparedness for future climate scenarios by facilitating adaptive reuse, enhancing cultural resilience, preserving traditional knowledge, and boosting tourism. The importance of restoring damaged heritage sites after an earthquake drew international attention to Nepal after the 2015 Gorka Earthquake. UNESCO established an office in Kathmandu to promote the restoration of tangible and intangible heritage in the area. This included developing structural analyses of buildings with historical and cultural value that due to their nature cannot be intervened with the same methodology as modern buildings. In this paper, the case study of the earthquake-damaged Gopinath temple, is discussed. First, an initial visual inspection phase and the following diagnosis of the structure are discussed. Then, the results from a series of static and dynamic structural analyses performed to determine the safety level of the structure, together with a sensitivity analysis, are presented. A sympathetic intervention proposal capable of increasing the temple safety level and based on the addition of timber plates, has resulted in substantial improvements of the lateral behavior of the structure. The proposed intervention is deemed sustainable and able to increase the resilience of the temple in the face of future hazards.

“…The simplified model can be used in the performance-based design of masonry buildings and for the assessment of existing masonry buildings and for low-rise masonry buildings. Rios et al (2021) conducted a discrete modeling approach based on a limit analysis, which is capable of reproducing sliding mechanisms, and highlighted that the method is applicable for masonry structures where sliding cannot occur, there is no tensile strength, and infinite compressive strength and failure can occur under small displacement. Rupakhety et al considered "Bal Mandir," which is an aggregate masonry complex located in Kathmandu, Nepal, for system identification using ambient vibration records taken after the Gorkha earthquake that significantly damaged the structure.…”

Enhancement of Himalayan irregular stone masonry buildings for resilient seismic design

In the Himalayan region of Nepal, stone masonry has been used for centuries as the primary building material for structures with or without mud mortar. In three distinct remote rural villages, a thorough structural survey of approximately 223 buildings was conducted with an emphasis on their structural irregularities. The thickness of masonry walls frequently varied between floors, which caused mass irregularities. Openings in the front wall of the buildings were not symmetrical in the vertical direction, which caused in-plane discontinuity. There were also out-of-plane offset irregularities due to the cross wall on the ground floor. These buildings were irregular in many aspects and were constructed without seismic considerations. This type of construction is more susceptible to earthquakes as a result of these irregularities. In this study, a thorough examination of a typical building was conducted using construction information obtained following the 2015 Gorkha earthquake. The database for each structural typology was prepared with an emphasis on construction practice to enhance the seismic design. The use of mud/cement mortar was extremely sparse, and the use of timber bands at various heights along the height of the masonry wall and an inappropriate connection between the wall and the roof were also negligible. The three main community-learned improvements following damage were the replacement of the gable wall with a metal sheet, the reduction of individual stone masonry homes to one story, and lighter construction on the upper stories of hotel buildings. Based on regional building techniques, non-linear finite models for typical and enhanced buildings were simulated. Due to the irregular stone units, construction variability, and constrained linear behavior, stone masonry with and without mud mortar presents difficulties in conducting a detailed numerical analysis. The development of these structures using mud/cement mortar and other regional materials, with careful attention to detail, was found to have significant potential as a seismically resilient building form.
