Mitigation of wind induced accelerations in tall modular buildings

چکیده
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 uncertain contribution global lateral stiffness damping. study analyses acceleration response Broadly speaking, for this approaches exist mitigate excessive vibrations; increasing dimensions or addition auxiliary evaluates these large number archetype structures order investigate method is more effective. Of than 6000 archetypes studied, it was found that over 40% required vibration control measures meet ISO limits. Installing Tuned Liquid Damper (TLD) proved significantly efficient RC dimensions; 1% increase damping achieves similar level reduction approximately 2100 mm breadth depth. The estimated available from TLD sufficient majority considered. A developing curves defining maximum feasible height building based on its provision an optimum also developed. results show used as viable construction high-rise quantify extent heights tower increased using existing technologies.

Learning Design Rules for Wind Bracings in Tall Buildings
This paper describes a methodology for applying machine learning to problems of conceptual design, and presents a case study of learning design rules for wind bracings in tall buildings. Design rules are generated by induction from examples of minimum weight designs. This study investigates the applicability of machine learning methods which are capable of constructive induction, that is of aut...
متن کاملAnalysis of Tall Buildings with Bundled Tube System Subjected to Wind and Earthquake loads
At present, the tubular structural systems are mainly used in tall buildings to withstand earthquake loads. Although it is possible to analyse the structure by finite element methods using standard three dimensional programs, the system is generally time-consuming and expensive in the primary design work. In this paper, for the analysis of Framed-Tube systems, a simple method was studied and de...
متن کاملOPTIMAL WIND RESISTANT DESIGN OF TALL BUILDINGS UTILIZING MINE BLAST ALGORITHM
Practical design of tall frame-tube and diagrids are formulated as two discrete optimization problems searching for minimal weight undercodified constraints under gravitational and wind loading due to Iranian codes of practice for steel structures (Part 6 & Part 10). Particular encoding of design vector is proposed to efficiently handle both problems leading to minimal search space. Two types o...
