The need of increased inspection of steel building structures (English)
Abstract [sv]

I arbetet undersöks behovet av ökad kontroll i stålbyggnadskonstruktioner med avseende på utförandefel. Riksdagen beslutade 1 juni 1994 att förändra Plan- och bygglagen (PBL) där förändringen trädde i kraft 1995 och bland annat innebar att hela ansvaret för en byggnads uppförande och kontroll lades på byggherren. Efter vintrarna 2009/10 och 2010/11 där flera tak rasade av snötyngden uppdagades en rad dimensionerings- och utförandefel. Under examensarbetet undersöktes vad som händer med säkerheten i byggnadskonstruktioner i stål som genomgår förändringar under dess livslängd och en jämförelse mot gällande regelverk genomfördes.

En fältstudie och flera intervjuer genomfördes där fokus låg på utförandefel och hur förändringar av regelverk lett fram till dagens egenkontrollsystem som påverkat antalet utförandefel. Arbetets resultat visar att det kan finnas ett behov av att se över dagens kontrollsystem och att antalet allvarliga utförandefel i fallstudieobjektet ökat efter 1995.

Abstract [en]

In the work the need of increased inspections of steel structures with respect to errors of execution was examined. On 1 June 1994, the Swedish parliament decided to change the Planning and Building Act (PBL) and the changes came into force in 1995, where the entire responsibility for the construction and control of a building was placed on the developer. After the winters of 2009/10 and 2010/11, when several roofs collapsed by the snow weight, a number of design and execution faults were discovered. During the thesis work it was investigated what happens to the safety of building structures in steel that undergo changes during its lifetime and a comparison with current regulations was made.

A field study and several interviews were conducted where the focus was on execution errors and how changes in regulations led to today's self-control systems that affect the number of execution errors. The results of the work show that there may be a need to review the current control system and that the number of serious execution errors in the case study object increased after 1995.
