Monitoring of structural health and safety of Flores hall and Valencia hall: Inputs for repair, renovation, and retrofitting phase II

The evaluation of structures is imperative as these structures age and exposed to different external and internal stresses and resistances. The strength of any structure inclusive of its structural components, can be determined from its health and safety. This study aimed to evaluate the structural health and safety of Flores Hall and Valencia Hall through the use of Non-Destructive Test specifically the Rebound Hammer Test and consequently propose Preventive Maintenance Management Plan. The researchers conducted non-destructive Rebound Hammer test to the structural components such as beams, bleachers, columns, and slabs of the two Halls. The results of the Rebound Hammer test were automatically produced, tabulated, and analyzed. For Flores Hall, most of the columns in the ground floor have existing condition of structurally sound which means above with the allowable compressive strength while in the second floor some of the columns have existing conditions of moderate, considerable, and major distress which were below the allowable compressive strength; in the beams and slabs, some of the grid lines have existing condition of structurally sound which were above the allowable compressive strength while majority of the grid lines have existing conditions of moderate, considerable, and major distress which were below with the allowable compressive strength. All the grid lines of the bleachers in Valencia Hall when tested by Hammer Rebound equipment yielded compressive strength above the allowable compressive strength of 28 MPa. Also, majority of the columns in Valencia Hall have existing condition of structurally sound which were above the allowable compressive strength but some of the columns have existing condition of moderate, and considerable distress which were below the allowable compressive strength. Furthermore, for the beams tested, all have existing condition of structurally sound which means above the allowable compressive strength. The Non-Destructive Test through the use of Hammer Rebound Test equipment to monitor the structural health and safety of Flores Hall and Valencia Hall yielded data in terms of the existing conditions of the beams, columns, slabs, and bleachers. The results of the Hammer Rebound test revealed the average compressive strength per grid or grid line of the structural components which show if the structural component complied with the allowable compressive strength. The proposed Preventive Maintenance Management Plan may be used to systematically implement the monitoring of structural health and safety of the Flores Hall and Valencia Hall and provide a safe structure where administrative officials, faculty members, students, and other stakeholders can perform their works and transactions.
