Decision-making on economic maintenance of earthquake-resistant reinforced concrete structures
It is necessary to repair or reinforce earthquake-resistant reinforced concrete structures during their service time since their safety performance may gradually deteriorate due to environmental factors such as concrete carbonation, steel erosion, natural aging, or earthquake damage. This paper adopts a benefit-cost analysis and puts forward an economic decision-making method on preventive maintenance, pre-earthquake reinforcement, and post-earthquake repair and dismantling of structures, with consideration to earthquake damage accumulation, natural aging, and durability damage. It is of crucial theoretical significance and application value to the decision-making on the maintenance of structures.
House Design Flood and Earthquake Resistant Recommender Application implementing Case-Base Content Filtering Algorithm
In this study we developed an application which can help the future and current residents of Marikina City, Architects and Engineers by providing a pre-defined Flood and Earthquake house design and infrastructure based on the National Structural Code of the Philippines.
 The application contains Geohazard Maps which are the Fault line Map, Flood Prone Areas Map and Zoning Map. Also the application will present the available lots within the Marikina City's Residential Zone. Along with recommendation of house designs, the estimated cost of the house will be calculated based on the standard budget estimates used by the Marikina City Planning Office.
 We implemented Case- Base Content Filtering algorithm for finding the best house design from user's input. The application will provide a pre-defined house designs based on user's input House Style, Lot size, Floor area and Number of Floors and present an available location within Marikina City's Residential Zone
Frequency selective surface design for blinds applications
In this paper, the reconfigurable blind structure with frequency selective surfaces(FSS) for the building applications are presented. Frequency transmission characteristics for different angles of the proposed blind-FSSs are investigated and verified through simulation and measurement. The simulation results show that we can implement the reconfigurable blind-FSS for multiband wireless applications. To verify the proposed paper, two kinds of blind-FSSs, crossed dipole FSS and circular ring FSS are fabricated and measurements are performed for different angles. The proposed structure in this paper which is very simple, can be easily applied to any planar surface for wireless security applications at low cost.
