Abstract

As a result of population density in Egypt emerged the importance of the use of tall buildings. Tall buildings increase the displacement of top floors due to lateral loads effect and increase the settlement due to vertical loads. A numerical analysis is carried out to analyse buildings with shear walls that have regular and staggered openings and resting on piles raft with different pile configurations under seismic action. The behaviour of soil-structure interaction, with weak soil profile, on superstructure of 20, 25, and 30 storeys and rested on a pile raft was investigated and was found to have a significant effect on the buildings. It was found that the openings in the shear walls have a significant effect on the values of the settlement. Also, the staggered openings are preferable more than the regular openings and the effect of pile length in clay soil is greater than the pile diameter.

地震荷载作用下带开口剪力墙高层建筑的土-结构相互作用

由于埃及人口密度的增加，高层建筑的使用显得尤为重要。高层建筑由于横向荷载的影响而增加了顶层的位移，由于竖向荷载的作用而增加了沉降。对具有规则交错开口的剪力墙和不同桩型的桩筏结构的建筑物在地震作用下进行了数值分析。研究了20层、25层和30层上层建筑以及桩筏上的土-结构相互作用行为，发现其对建筑物有显著影响。研究发现，剪力墙中的开口对沉降值有显著影响。此外，交错开孔比规则开孔更可取，并且粘土中桩长的影响大于桩径。

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.
