Geo-DBMSs make it possible to manage large spatial datasets in databases that can be accessed by multiple users at the same time. These spatial datasets usually contain 2D data, while more and more applications depend on 3D data. Some examples are 3D cadastres [1], telecommunications [2] and town planning [3]. These applications mainly come from the ever-growing tendency of using living space m...

The paper aims to investigate the accuracies of idealization methods well-known shear-building models. Five are adopted idealize structural story capacity curve within range from zero deformation corresponding peak shear point. After point, a skew branch followed by constant used approximate curve. five verified using four reinforcement concrete (RC) frames with 3, 8, 12, and 18 stories. Result...

Cadastral systems are mission critical systems designed for the registration of parcels, buildings and apartments as well as their owners and users. The maintenance of real estate cadastre registers is in Poland dispersed. So the attempt to create a unified cadastral system is one of the goals of Polish government. Two main IT projects aimed at the creation of an integrated system are presented...

Hexagrid structural system is an innovated system with structural behavior which is similar to a tubular system. In this paper, a numerical study is conducted to estimate the seismic performance of horizontal hexagrid concerning the combined horizontal and vertical hexagrid, tubular and diagrid structural systems. First 30 and 50 story buildings are modeled using ETABS, then pushover and nonlin...

In this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. The designed base was according to provisions of the Canadian standard, 2005 NBCC. The behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. These models c...

During on an extensive investigation of a multi-story timber building with light-frame construction, several stages of the building process and their impact on sound transmission were observed. The sound insulation properties of the building components were measured before and while the buildings were occupied. Furthermore, interviews with the occupants were conducted. This procedure made it po...

This study presents levels of volatile organic compounds (VOCs) measured indoors for the first time in Ulaanbaatar, Mongolia, and quantifies health risk children emphasizing urgent need to improve control indoor VOCs sources. The 583 samples collected at 144 sites, including new buildings, old apartments, schools, workplaces, kindergartens, baishin, Mongolian traditional gers, hospitals, shoppi...

The Japanese architect Yoshikazu Uchida planned the estate plan of Osaka Hokko Co. Ltd. from 1920 to 1922. Through this study, we aim clarify Uchida’s for outdoor spaces such as roads, parks, and plazas, his ideology on them considering plan. To achieve purpose, analyze letters sent mostly corporate insiders Uchida, planning documents, four drawings. results show that used conflicting ideas dep...

Recent advances in the development of a wave travel time methodology for earthquake damage detection in buildings, for use in rapid assessment of structural health following an earthquake, are reviewed. Its main advantages over the modal methods are the insensitivity to the effects of soil-structure interaction, local nature, and robustness when applied to real structures and strong earthquake ...

This work represents an effort to develop one plausible realization of the effects of the scenario event on tall steel moment-frame buildings. We have used the simulated ground motions with three-dimensional nonlinear finite element models of three buildings in the 20-story class to simulate structural responses at 784 analysis sites spaced at approximately 4 km throughout the San Fernando Vall...
