STRUCTURAL EVALUATION IN ORDER TO INCREASE THE NUMBER OF FLOORS IN THE INTEGRATED LABORATORY BUILDING AT LAMBUNG MANGKURAT UNIVERSITY

Abstract

A building's chance of experiencing structural failure may rise as its floor count rises. This occurs as a result of buildings having a maximum load capacity. A structural examination was conducted in the Integrated Laboratory building at Lambung Mangkurat University to determine the condition of the structure if further stories were added.

Three load variations are added to the building, ranging in size from the smallest (1 level) to the largest (3 floors), in order to evaluate the construction. The structural elements' size remains the same while the number of floors is increased. An analysis is conducted for each load variation, taking into account the structural elements' capacity, the fundamental period, story drift, and the number of modes needed to achieve the mass participation mandated by the building standards.

The analysis conducted with three load variations revealed that the column, beam, and slab structural elements can still support the load placed on the structure if three floors are added. However, the working load on the foundation structural elements has exceeded the capacity of the existing foundation to support three floors of additional buildings; the foundation can only support one additional floor. Aside from that, the analysis's findings indicate that the value of the story drift, the fundamental period, and the number of mode shapes required to meet the modal participant mass ratio mandated by building regulations all increase with a building's floor count.
