This paper compares two methods of mitigating wind induced vibrations in tall modular buildings. Tall buildings experience motion which can result serviceability and habitability issues associated with occupant discomfort. Modular construction, volumetric modules are assembled around a reinforced concrete core, be particularly susceptible to accelerations due the slender form core small uncerta...

In this paper the dynamic response of tube-in-tube systems for tall building structures is investigated. Inner and outer tubes are modeled using equivalent continuous orthotropic membranes; in which, each tube is individually modeled by a cantilever box beam. By applying the compatibility conditions on deformation of the two tubes, the governing dynamic equations of the tube-in-tube structure a...

Random vibration analysis of tall structures faces multiple problems due to the large number of elements and high degrees of freedom; that is why this type of analysis is mostly used in simple structures and low degrees of freedom. In the past two decades, changes have been occurred in this type of analysis to be used in complex structures and the large number of elements. Pseudo-Excitation Met...

The construction of tall and slender buildings has seen recent growth in many cities around the world. Tall are susceptible to dynamic excitation under wind effects which typically govern structural design for strength, stability, serviceability. This paper presents state art analysis against effects. Structural criteria discussed detail, with serviceability relating occupant comfort noted as b...

The main objectives of the research are to characterize the wind-induced resonant and slowly-varying (quasi-static) responses of a tall building under ambient wind excitations based on GPS measurements. The equipment used includes two sets of orthogonally aligned accelerometers, two GPS receivers and an ultrasonic anemometer. The natural frequencies of the wind-induced vibration of the tall bui...

results of damage prediction in buildings can be used as a useful tool for managing and decreasing seismic risk of earthquakes. in this study, damage spectrum and c4.5 decision tree algorithm were utilized for damage prediction in steel buildings during earthquakes. in order to prepare the damage spectrum, steel buildings were modeled as a single-degree-of-freedom (sdof) system and time-history...

Orthophoto imagery is a valuable layer in a GIS because it provides a generic, inexpensive, and accurate base map. However, in cities with tall buildings it is difficult to create a seamless database of orthophoto imagery. Traditional methods for orthophoto rectification disregard buildings. In this paper, we describe a fully automated process, developed by ASI, that creates true orthophotograp...

On the basis of existing test data high temperature mechanical properties 1860 grade steel strands, a regression model performance strands that can be used for theoretical analysis and numerical calculation is obtained. Based on non-stationary field in fire tall large space buildings, non-linear finite element method considering time integral effect to establish resistance large-span prestresse...

Due to the shortage of land in cities and population growth, significance high rise buildings has risen. Controlling lateral displacement structures under different loading such as an earthquake is important issue for designers. One best systems diagrid method which built with diagonal elements no columns manufacturing tall buildings. In this study, effect distribution tuned mass damper (TMD) o...
