STRUCTURAL EVALUATION OF THE MELATI HOSPITAL BUILDING AT SUNGAI PENUH CITY, INDONESIA

Abstract

Melati Hospital is one of the health buildings in Sungai Penuh City, Jambi Province, Indonesia. The building, which was previously the main maternity clinic, is going to be upgraded its status to a maternity hospital. Based on the field investigations, the concrete compressive strength (f’c) was 15.77 MPa, which did not meet the requirement in the Indonesian building codes. Therefore, a structural evaluation should be done on the building structure. Structural analysis was performed with ETABS v18 software using two methods, the open frame and the masonry infilled-frame methods. The performance of the building structure was evaluated in terms of the moment and shear capacities in columns and beams, as well as the inter-story drift in the existing building. The results obtained by modeling the structure as the open frame found that the capacity of the existing structure was not strong enough to resist the working loads, especially on the second-floor columns, beams, and inter-story drift that did not meet the permitted limit in the building codes. Meanwhile, the modeling of the structure used masonry infilled-frame, this hospital building structure is strong enough to withstand the working loads. From the results, it was found that the ability of this building to resist earthquake loads largely depends on the wall's contribution to withstand lateral loads. The masonry is a brittle material that is prone to crack or failure so the retrofitting of the masonry wall using ferrocement layers is highly recommended for this hospital building.
