Serviceability of buildings is affected by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. To ensure functional performance of tall buildings it is important to keep the frequency of objectionable motion levels below the discomfort threshold. This paper addresses a new approach that facilitates mitigation of wind induced motion of ...

This paper investigates the twisted wind effect on a typical super-tall building (500-m-tall square prism) by conducting pressure model tunnel tests. Two fields (TWFs) with maximum yaw angles of approximately 30° and 20°, respectively, near ground level were generated in using guide vane system, test results load TWFs compared those obtained conventional (CWFs) constant direction along vertical...

Most tall buildings use glass as its façade and exterior materials, which makes the building's envelope is exposed to heat penetration. It important select design proportion between transparent opaque materials for building reduce gain from outside, strategic conserve energy buildings. This study aimed observe of in accordance with effort order AC system. The modification calculated by using Ov...

In this paper, a ‘‘third generation’’ benchmark problem that focuses on the control of wind excited response of a tall building, using the Model Predictive Control ~MPC! scheme, is presented. A 76 story, 306 m tall concrete office tower proposed for the city of Melbourne, Australia, is being used to demonstrate the effectiveness of MPC. The MPC scheme is based on an explicit use of a prediction...

Landscape is the visible cognition of human environment, including natural objects such as mountains, rivers, the sea, forests and artificial objects such as buildings, bridges, and other structures. Landscape can be recognized and evaluated differently, depending on the viewer. However, people who share the same or similar local culture or aesthetics have the common recognition and evaluation ...

Building on the economic research that demonstrates a positive relationship between height and worker ability, this paper compares the wage returns to height for immigrants and natives to explore possible explanations for the positive wage-height gradient. Using multiple data sets, the paper presents a robust empirical finding that the wage gains associated with height are almost twice as large...

A damage detection method utilizing Support Vector Machine (SVM) for bending structures is proposed. The SVM was recently proposed as a new technique for pattern recognition. The SVM is a powerful pattern recognition tool applicable to complicated classification problems and is effectively utilized in the method. Based on the modal frequency changes, the damage location and its severity are def...

In a tall building with multiple elevators, it is a notoriously di cult task to control the elevators in the most e cient manner [1].The system proposed in this paper contains two key ideas. First, it continuously generates dispatch functions by adaptation to changes in passenger tra c. Second, it tries to reduce passengers' waiting time by multiple elevator allocation when it is expected that ...
