INTRODUCTION Project Background Extreme wind events such as typhoons are continually projected to rise in severity due to the increasingly alarming effects of climate change (Dinan, 2017). In the recent years, the Western Pacific has seen a frequent number of devastating super typhoons which severely struck Southeast Asian countries and caused a staggering number of casualties (Pantua, Calautit, & Wu, 2021).

Moreover, these calamities are essentially displacing many families and residents from their homes – and with the lack of proper implementation of risk reduction operations, they are left unprotected against the danger of severe conditions within their areas.

In the Philippines, increasing typhoon intensities have similarly been a primary concern for families dwelling on typhoon-vulnerable regions. In assessing the structural damages brought upon by super typhoon Yolanda, the study conducted by Chen et al. (2016) has reported that more than 50% of typhoon failures was caused by high wind damage; similarly, more than 20% of the damages was reported as roof failures attributed to high strength winds. But despite these literature on structure’s vulnerabilities to typhoon wind loadings, low-rise residential structures around vulnerable areas continue to be constructed with less rigorous engineering designs and inadequate considerations on lateral force effects. Roof mitigation strategies that have been employed are also often found to be unsuccessful, and the implementation of devices in some structures has only caused even more damage as wind-borne debris. These clearly indicate the need for low-rise residential structures in typhoon-prone areas to explore further methods that will secure their stability and resistance to extreme wind events.

2

In this regard, aerodynamic optimization of building shapes is seen as a possible solution for efficiently resisting winds, although such methods are yet to be popular in low-rise structures. By modifying a building’s geometry during the early design stages, a structure can be constructed and designed such that it will reduce wind responses especially during typhoons where wind loadings are extremely significant. Specifically, Cooper et al. (as cited

by Yi et al., 2021) suggest that tapering the cross-section of the building to an optimal geometry can minimize across-wind responses by spreading out the excitation magnitude over a wider range of wind speeds.

These engineering solutions have emerged the idea of an “Egloo” house, an egg-shaped residential structure resembling an igloo, whose geometry will be designed to potentially resist extreme winds from typhoons. The complexities of Egloo’s curved geometry, however, may restrict the use of conventional materials such as concrete hollow backs (CHB); hence, an alternative material – Po-Lite Panels – will be utilized. These Po-Lite products are engineered green materials developed by a Filipino-owned company, Po-Lite Technology Inc., whose convenient customization and installation methods make them suitable as a potential construction material for Egloo houses.

Project Description Structural Design and Construction of Egloo Residential Houses using Po-Lite Panels in Maasin, Leyte Maasin, Leyte This project aims to deliver structural designs and construction plans for an Egloo residential house designed to resist extreme lateral loadings – particularly wind and earthquake – in the city of Maasin in Southern Leyte, being one among the worst-affected areas by the recent Super Typhoon Odette that struck in 2021. The house shall be constructed using Po-Lite Tiles over a 36 sq. m. lot area, and they shall also comply with the minimum standards for a loft structure. Additionally, the structural analysis and design of this project shall be conducted using STAAD.Pro. High-quality experiments and wind tunnel facilities are nearly limited in the Philippines, hence numerical simulation tools such as Finite Element Analysis (FEA), particularly Computational Fluid Dynamics (CFD) simulation, are also selected to execute the necessary wind load evaluations and structural response.

Project Scope This section specifies the scope and the proposed “3BIRDS” component of the project: Three (3) fields of Civil Engineering, Beneficiary, Innovation, Research, Design, and Sustainability - although the Design and Sustainability components will be discussed in the latter parts of the book.

Dr. Ria Liza C. Canlas Project Beneficiary

The direct beneficiary of this project shall be Dr. Ria Liza C. Canlas, CEO and Founder of Po-Lite Technology, and the primary beneficiaries shall generally include the residents of Maasin, Leyte.

Fields of Civil Engineering The project shall comprise one (1) major area – Structural Engineering (STE) – and two (2) minor areas namely, Construction Engineering and Management (CEM) and Environmental Engineering.

The STE and CEM aspects respectively cover the structural analysis and the construction plans integrated in this proposal, while the Environmental Engineering is reflected by the project’s utilization of green products as its major construction material.

INNOVATION The Egloo Po-Lite House will deviate from the traditional shapes of residential structures, as it will follow a novel egg-shaped form that is optimally designed to resist extreme typhoon wind loadings in the selected area. Additionally, Po-Lite Panels shall be innovatively used as a major construction material. These Po-Lite products are newly engineered green materials designed as a replacement or alternative to conventional concrete. The installation of these panels requires less work, as the process is not labor intensive, and its customization allows the client to tailor the material’s specifications and physical properties according to the proposed structure.

RESEARCH COMPONENT The project incorporates the group's ongoing thesis study about the structural analysis of Po-Lite structures in resisting typhoon wind loads by analyzing certain low-rise structural tapered models with different geometry and evaluating their response to vortex shedding through FEA. Specifically, this research component shall also entail an examination of the Egloo Residential House's geometry and its resistance to wind loads.

The use of Po-Lite panels as the primary material in this project shall be accompanied by an assessment of their resistance to wind and seismic stresses.

Significance of the Project The purpose of this project is to design an egg-shaped structure that can resist wind lateral loads while incorporating prefabricated innovative materials. As this project is focused on the Structural Design and Construction of Egloo Residential Houses using Po-Lite Panels, it will mainly help in strengthening the structure quality and economic life of residential houses in Maasin, Leyte.

Specifically, this project will benefit the Environment, Residents of Maasin, Civil Engineering Students, ADEQUATE Engineering Services, Construction and Structural Firms, Beneficiary, and the Po-Lite Technology Inc. 5

LOADINGS The topographical and geological qualities of the chosen location influence the design and construction of this project. Further, the following technical specifications presented below shall be put into consideration in the design and construction of Egloo Residential Houses.

Nature of Occupancy 2

As per Section 103.1 of the NSCP 2015, the nature of occupancy of Egloo Residential Houses shall be considered as Occupancy Category IV as it is classified under Standard Occupancy Structures (Residential).

Wind Loads

2

Wind loading is a significant factor in the structural design of Egloo Residential Houses as it influences the structure's strength in resisting lateral loadings. As presented in Figure 207A.5-1A of the NSCP 2015, the location of Maasin, Leyte falls under the contour line whose basic wind speed is 290 kph. Furthermore, the structure's design shall be governed by the basic wind speed presented.

Seismic Loads 2

Identifying seismic loads play an important role in the design of the structure as it facilitates in estimating the structural response in the process of designing an earthquake-resistant structure. The project location falls under Zone 4 of the seismic map. In relation to this, the nearest active fault trace from the project’s location was determined using PHIVOLCS’ Fault Finder Application. The said fault trace is known as the North Mindanao Sea Fault and is situated 18.7 km away from the location of the project.

Arc Lengths = 1.47 m; 1.46 m Lengths = 0.52 m; 0.53 m

Arc Lengths = 0.92 m Lengths = 0.53 m 18

CFD Simulation: Velocity Profiles The velocity profile of the structural models in the simulation provides information about the flow of fluid - in this case, air - within a structure. This information can be used to determine if there are areas of high velocity, low velocity, or no flow at all. This also determines how much flow there is in each area and how fast it is flowing.

The Egloo Residential Model (4th Figure) yielded the lowest fluctuations in velocity. Low turbulence was also observed from the simulation of the Egloo model.

19

CFD Simulation: Turbulent Kinetic Energy Profiles The Turbulent Kinetic Energy Profile quantifies the energy of the turbulent flow on the structures. The gradient in the contours of the profile signifies the amount of turbulence. A red contour on the profile signifies maximum turbulent kinetic energy while solid blue contours denote minimal to zero kinetic energy.

The Egloo Residential Model (4th Figure) had minimal turbulence as shown in its turbulent kinetic energy profile.
