A Comparative Finite Element Analysis of a Two-Story Residential Building Using Concrete Hollow Blocks and Po-lite Hollow Blocks

This paper presents a comparative linear static, and dynamic analysis of two types of models of a two-story residential building considering three essential parameters: stress, and displacement. The first model utilizes a Concrete hollow block (CHB), while the second model utilizes Po-Lite hollow block (PHB), both with concrete structural components. The models were subjected to Finite Element Analysis (FEA) using MSC Patran and Nastran, considering dead load, live load, and wind load with pre-determined dimensions and material properties for each structural element. Based on the FEA, it has been determined that the PHB model is significantly superior when it comes to stresses imposed on the structure. However, it is also revealed that the CHB model is significantly superior in resisting deflections and deformation. Furthermore, the utilization of Po-lite leads to cost-efficiency as it eliminates other construction scope of work such as finishing works. Because of this, it only requires fewer construction processes than conventional construction, which reduces labor time and construction costs.
