Differential settlement between vertical structural elements of steel and concrete in tall buildings : Time dependent deformations in concrete elements due to load history, creep, shrinkage and elastic deformations and elastic deformations in steel columns. (English)
Abstract [sv]

I höga hus, i storleksordningen 100 m och högre, med vertikalbärande stomme av stål och betong kan differentialsättningar uppstå då de olika materialen deformeras olika. Detta ger med tiden lutande bjälklag.

I det här arbetet har ett beräkningsprogram tagits fram med hjälp av Mathcad för att räkna ut de slutliga deformationerna och hur mycket man behöver kompensera för skillnaderna i deformation genom att gjuta bjälklagen med fall. Programmet är tänkt att användas av WSP i projekteringen av höga hus.

Med hjälp av programmet har parametriska studier gjorts och det visade sig att genom att ändra på vissa parametrar kan differentialsättningarna utjämnas. I vissa fall kan detta medföra att gjutning med fall ej är nödvändigt.

Abstract [en]

When high buildings are built with steel and concrete collaborating, some problems may occur because the materials deform differently. The differences in the final deformations make horizontally casted floors start to lean over time.

In this study a program has been developed in Mathcad to calculate the final deformations and differences. The differences can then be compensated by casting the floor with a slope. The program is supposed to be used by WSP to project high buildings.

The program has been used for some parametric studies to show how different parameters can decrease the differences. If this makes the differences small enough it will not even be necessary to cast floors with a slope.
