Comparison of Testing Results of Three Poorly Streamlined Entertainment Venues / Trijų Sudėtingo Pavidalo Pramoginių Statinių Maketų Bandymų Rezultatų Gretinimas

Abstract

Abstract. The article discusses experimental investigations of wind effects and use of design codes for solving aerodynamic problems. It provides data regarding wind-tunnel tests conducted on three buildings with poorly streamlined shapes, including: methodology and test conditions, aerodynamic properties of the designed structures, features of physical models and research results. All three civil buildings are multi-purpose stadiums of the European level. Despite the identical functional purpose, each building has a unique shape and volume. The paper analyses and compares testing conditions in the wind tunnel and some selective results. The authors propose a criterion for estimating aerodynamic properties of the overhanging roof over spectator stands. The article also considers dependencies of model surface pressures on airflow directions under various test conditions.

Design Revisions of Complex Building Structures: Work Experience in Lithuania, Legislative, Organizational and Technical Aspects

“…A technical project has to be detailed enough in order to be in conformity with valid regulations (STR 1.05.06:2010): -understand the project concept; -verify main decisions in expertise; -estimate the construction price; -select a general construction contractor; -get a building permit; -execute a working project. Solving of design questions originated when performing surveys, additional investigations (for example, a building model test in an aerodynamic tube, Pavlovsky et al 2012), demounting of existing structures and all the above-mentioned procedures are implemented during the technical project stage. The final technical project is delivered to the client (builder) as a separate set of documents.…”
