1. Load-Carrying Capacity of Steel Girders and Panels with Thin-Walled Trapezoidally Corrugated Webs
Sammanfattning : This thesis concerns the load-carrying capacity of steel girders and panels with thin-walled trapezoidally corrugated webs. Computer-based numerical methods are used as a tool and emphasis is placed on various parametric studies, covering geometric parameters, initial imperfections, material strain-hardening models, loading types and loading positions, and so forth.

2. Serviceability Limit State for Steel Girders during Bridge Launching - A Patch Loading Problem
Sammanfattning : Incremental launching is a construction method in which bridge girders are first assembled in the vicinity of the future permanent position of the bridge. When the elements have been welded together the girders are launched to their permanent position. LÄS MER
3. Mechanics of paper webs in printing press applications
Sammanfattning : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. LÄS MER
4. Stability of statically and periodically loaded structures
Sammanfattning : In this thesis different kinds of stability phenomena are analysed. Firstly the quasi-static behaviour of an elastic structure is studied for increasing loading. LÄS MER
5. Structural Analysis of Deep Composite Box-Type Components with application to a proprietary stabilising timber wall element
Sammanfattning : The stabilising wall element of the Trä8-system is a deep box-type beam/column element which is made of different types of timber composites including framing members of gluedlaminated timber (glulam) and sheathings of laminated veneer lumber (LVL). This element is used as a ―shear wall‖ in multi-storey buildings up to four storeys. LÄS MER
