  1. 1. Modelling of temperature, moisture and stresses in young concrete

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan-Erik Jonasson; Luleå tekniska universitet.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The present study consists of three areas, namely modelling of- (1) temperature, (2) moisture state, and (3) stresses in young concrete. The derivation of models, examination of material data, and development of computer programs have progressed differently in these areas. READ MORE

  2. 2. Structural Identification of Civil Engineering Structures

    University dissertation from Luleå tekniska universitet

    Author : Tarek Edrees; Luleå tekniska universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The assumptions encountered during the analysis and design of civil engineering structures lead to a difference in the structural behavior between calculations based models and real structures. Moreover, the recent approach in civil engineering nowadays is to rely on the performance-based design approaches, which give more importance for durability, serviceability limit states, and maintenance.

  3. 3. Restraint in structures with young concrete Tools and estimations for practical use

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Majid Al-Gburi; Luleå tekniska universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. READ MORE

  4. 4. Restraint Effects in Early Age Concrete Structures

    University dissertation from Luleå tekniska universitet

    Author : Majid Al-Gburi; Luleå tekniska universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. READ MORE

  5. 5. Measurement and modelling of young concrete properties

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Peter Fjellström; Luleå tekniska universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The main aim of this thesis is to refine models for strength and heat development of the young concrete, and evaluate if developed models at Luleå University of Technology (LTU) for creep, autogenous shrinkage and thermal dilation needs refinement. These are of importance in hardening control and in crack control of a concrete structure. READ MORE
