  1. 1. Load-Carrying Capacity of Damaged Concrete Structures

    Författare :Kamyab Zandi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frost; bond properties; material properties.; Existing concrete structures; load-carrying capacity; corrosion of reinforcement;

    Sammanfattning : AbstractA growing need for better assessment of existing structures has revealed the need for improved understanding of structural effects of deterioration. The two most common causes of deterioration in concrete structures are corrosion of reinforcement and freezing of concrete. LÄS MER

  3. 2. Load carrying capacity of bridges : three case studies of bridges in northern Sweden where probabilistic methods have been used to study effects of monitoring and strengthening

    Författare :Anders Stenlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Probabilistic methods are presented for the assessment of bridges. Load carrying capacity calculations and evaluations of strengthening methods are carried out for three road bridges in northern Sweden: 1) The E4-bridge over Pite River - A four span steel beam bridge with a concrete deck built in 1969.

  4. 3. Load-Carrying Capacity of Steel Girders and Panels with Thin-Walled Trapezoidally Corrugated Webs

    Författare :Ruoshan Luo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; finite element; thin-walled structures; girder; post-buckling; panel; trapezoidal corrugation; load-carrying capacity; optimal design; plasticity; spline finite strip; buckling; large deflection;

    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.
