Abstract [en]

The thesis aims to analyze and compare two frame systems, based on the stabilization

against horizontal loads.

The fictitious object of study that forms the basis for the analysis is a 10-storey timber

building. Common to both systems is that the first floor is a concrete structure and

the other nine stories are constructed with solid timber. What distinguishes the

systems from each other is that in one of them the elevator shaft and stairwell are

constructed with concrete.

The systems are analyzed by the finite element method on the basis of the calculation

software FEM-Design 3D Structure. The objective is to investigate the effects created

by horizontal loads and the influence that a concrete core has on the stability of the

building. The goal of this thesis is to investigate if the object of study achieves an

acceptable stabilization and if the concrete tower is necessary.

The results of calculations in FEM-Design show that sufficient stability can be achieved

without a concrete core. However the analysis indicates that the concrete core has a

large impact on the stability of the building. The presence of the rigid concrete core

leads to reduced horizontal deformations enabled by redistribution of a significant

portion of the loads. Although, the slightly eccentric position of the core gives rise to

a rotation of the building when exposed to wind from a certain direction. The

consequence of this rotation is a significant reduction in the intended effects of the

concrete core, which also means that a large part of the concrete capacity is lost.
