Structural investigation of the Malate Catholic Church 2014 illustrations Malate Church underwent several repairs due to damages caused by typhoons, earthquakes and even wars. It was also observed that there was an intervention in the buttresses and walls of the right wing of structure that caused cracks and loosening of the masonry units. The damaged buttresses were sandwiched with steel reinforcements were corroded, causing further cracks in the masonry around the said reinforcements. The intent of this structural investigation is to determine the vulnerability of the structure based on the potential hazards due to wind and earthquake that may occur at the site. The equivalent forces that may act on the structure due to these hazards are stated in the referral Code, the National Structural Code of the Philippines. To achieve this goal, collection of data at at the site and material testing were thoroughly done in order to simulate the approximate behavior of the structure. Also, the structure was meshed into small solid elements approximately 1.0 meter cube and were analyzed using the Finite Element Method. Based on the results of the analysis, the maximum compressive and tensile stresses occur between the interface of the footing and buttresses. This means that the buttress, as a rigid structural element, resists more stress than the walls and cantilevers from the footing. Also, the maximum stress generated in the fabric is due to seismic force acting perpendicular to the plane of the wall. This is because the wall, though analyzed as a solid element, is slender compared to its height. For seismic force acting parallel to its plane, the behavior is similar to a shear wall, thus, producing minimum stress in the fabric. Finally, the maximum compressive and tensile stresses generated in the fabric are 0.80 MPa and 0.53 MPa, respectively. Based on the test, the ultimate compressive strength of the masonry unit is 4.86 MPa and tensile strength is 0.97 MPa. These values yield a factor of safety equal to 6.0 in compression and 1.8 in tension. These values are greater than the value normally used in the design of buildings with an average of 1.4. Thus, the structure can still resist the forces due to the design loads stated in this report provided that cracks and other damages present in the structure will be restored properly.
