摘要

屋顶形状和屋顶坡度都是保护结构免受风荷载影响的重要约束条件。本研究旨在研究锥形屋顶上风压系数的变化，并观察建筑物周围的风行为。CFD（计算流体动力学）软件ANSYS已被用于建模和仿真。研究发现，35°屋顶坡度是本研究的最佳屋顶角度，因为该屋顶角度的面积加权平均压力系数最小。而在本研究的所有屋顶角度中，30°的屋顶坡度被认为是风荷载阻力方面最关键的屋顶角度。

Numerical simulation of a conical roofed low-rise building to estimate the wind pressure coefficients

The roof shape and the slope of the roof are both significant constraints for the protection of the structure against wind load. The present study aims to investigate the variation of wind pressure coefficients on the conical roof and to observe the wind behavior around the building. CFD (Computational Fluid Dynamics) software ANSYS has been used for modeling and simulation. It is found that the 35° roof slope is the optimum roof angle for the present study, as there is the least area-weighted average pressure coefficient for this roof angle. While the roof slope 30° is found the most critical roof angle in terms of wind load resistance among all the roof angles of the present study.

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
