Diagnosis and structural intervention of an old estate hull in the Tarímbaro County, Michoacán

Diagnosis and structural intervention of an old estate hull in the Tarímbaro County, Michoacán A structural intervention proposal is presented for a segment of a twentieth century building that presents damages due to a drain of graded materials built in an earlier retrofit; the damage increased when the building was subjected by the September 19, 2017 earthquake. Currently, the building is used as a clubhouse in a well-known residential area located in Tarímbaro, Michoacán, México. The structure is composed of irregular stonework walls joined with mud mortar. The building’s original cover roof consisted of wooden beams, lower shingle, terrace and a brick upper cover that was replaced in the 1970’s by a solid reinforced concrete (RC) slab.

On the other hand, it provided a beneficial effect by keeping tied the walls damaged by the severe ground settlement generated in the eastern façade, caused by water seepage into the drain built without an adequate exit to the existing original drainage system in the construction.

Abstract

A structural intervention proposal is presented for a segment of a twentieth century building that presents damages due to a drain of graded materials built in an earlier retrofit; the damage increased when the building was subjected by the September 19, 2017 earthquake. Currently, the building is used as a clubhouse in a well-known residential area located in Tarímbaro, Michoacán, México. The structure is composed of irregular stonework walls joined with mud mortar. The building’s original cover roof consisted of wooden beams, lower shingle, terrace and a brick upper cover that was replaced in the 1970’s by a solid reinforced concrete (RC) slab. RC slab provided a high stiff horizontal diaphragm that could have contributed to the increase in wall cracking during the 2017 earthquake, due to the incompatibility of both materials. On the other hand, it provided a beneficial effect by keeping tied the walls damaged by the severe ground settlement generated in the eastern façade, caused by water seepage into the drain built without an adequate exit to the existing original drainage system in the construction. Based on the recommendations of the International Scientific Committee ISCARSAH of ISCARSAH (International Scientific Committee for Analysis and Restoration of Structures of Architectural Heritage. Recommendations for the Analysis, Conservation and Structural Restoration of Architectural Heritage - ICOMOS, France. https://iscarsah.files.wordpress.com/2014/11/iscarsah-guidelines.pdf, 2003), a qualitative and quantitative diagnosis of the structure is presented using a methodology based on a mesh of finite elements with linear behavior. The results showed that current damages appreciably reduced the building safety, so a retrofit proposal for the foundation and walls is presented, which was carried out successfully.
