Elastic properties of Icelandic concrete

Second milestone report, work done by Mannvit Testing & Research Lab in collaboration with Reykjavik University and The Icelandic Road Administration office.

Comparison of penetration resistance to PDR and pile capacity. Author; Guðmundur Þorsteinn Bergsson.

Pile driving reports from eight bridge foundations were examined. The focus was on whether there is a relationship between pile driving resistance and resistance in dynamic sounding (dynamic probing test (DP)) and whether it is possible to use the results to estimate the pile capacity. 

Analysing the effects of earthquakes on wind turbine. Author; Oliver Claxton.

The aim of the research is to gain insight into the importance of earthquake action for wind power installations as well as attain improved understanding of the dynamic behaviour of wind turbine structures. 

The dynamic behaviour of multi-story reinforced concrete building in a seismic and windy environment. Author; Örvar Jónsson.

In the report a 14 storey tall, reinforced concrete, office building is analysed and compared with results from monitoring system, which has been used to record the acceleration response of the structure in about 24 years.


Bearing capacity, relaxation and finite element simulation for prestressed concrete beams reinforced with BFRP tendons.  Author: Andri Gunnarsson

Experimental results considering prestressed BFRP reinforced concrete (RC) beams, were reviewed andcompared with formulations, regarding shear capacity, from codes and guidelines. The experiments were also simulated in the finite element (FE) program ANSYS.

Elastic Properties of Icelandic Concrete . Author: Guðni Helgason
The focus of this research to determine if there is cause to reconsider, partly or entirely, the instuctions given in the Icelandic national annex as a part of IST EN 1992-1-1:2004. Modeling of concrete cylinders in the computer program ANSYS is also performed.The thesis on pdf (in Icelandic)

Continuous Basalt Fiber as Reinforcement Material in Polyester Resin. Author: Jón Ólafur Erlendsson
This research investigate the material characteristics of a relatively new material, continuous basalt fibers in polyester resin. The results shown that basalt fibers can be used as reinforcement material in polyester resin, to create a composite structural material with acceptable engineering properties The thesis on pdf.

Capacity of concrete beams prestressed with BFRP tendons. Author: Sindri Hlífar Guðmundsson
To investigate the moment capacity of BFRP prestressed concrete sections, four beams were casted, with shear span to depth (a/d) ratio of 10,67. They were tested under two point static loading.The thesis on pdf.

Effects of soil-structure interaction on the excitation and response of a medium-rise reinforced concrete building. Author: Hannes Garðarsson
In the project a 13 storey reinforced concrete residential building is examined. Monitoring system has collected acceleration data in the building since 2007. System identification of the structure is performed based on earthquake recordings from the data set. The thesis on pdf.

Response of linear-elastic structures to near-fault ground motions. Author: Kristján Ingi Ólason
In this study the main characteristics of near-fault ground motions are addressed. Time-history analyses are performed for linear-elastic steel frames of five different heights. The dataset used in this study contains acceleration records from 27 different earthquakes with total of 56 records. The thesis on pdf.

Shrinkage of concrete. Author: Eva Lind Ágústsdóttir
Several different concrete mixes were made and concrete prisms casted for research. The research relates to various aspects relevant to either the mixing of the concrete itself or its treatment. These factors were: aggregates, cement, curing, cement paste, color admixtures, shrinkage reducing admixture, water-cement ratio and air content. The thesis on pdf.

Experimental research on strengthening of concrete beams by the use of epoxy adhesive and cement-based bonding material. Author: Sólrún Lovísa Sveinsdóttir
An experimental investigation was conducted on shear behaviour of RC beams that are strengthened using BFRP external reinforcement with epoxy resin as bonding agent. This experimental test program is set up to test the shear capacity of beam specimens. Link to thesis.

Experimental research on BFRP confined concrete columns. Author: Arngrímur Konráðsson.
The primary objectives of this research are to investigate the behaviour of axially loaded concrete columns confined with an obscure material in civil engineer for strengthening, basalt fibre reinforced polymer jacket (BFRP), and to compare calculation predictions to the test results using available guidelines.

Prestressed BFRP tendons in concrete beams. Author: Björgvin S. Jónsson.
The main topics of this experimental work are to use prestressed BFRP tendon as reinforcement in concrete beam, simulating precasted slabs for example, and try to estimate the relaxation of the prestress force in the tendon. Link to thesis.

Confined concrete with Icelandic aggregate. Author: Páll V. Bjarnason.
This thesis presents a study of the behavior of large scale concrete columns confined by rectangular ties under concentric loading.The main focus is on using Icelandic cement and aggregate and to find out if the ductility and compressive strength of Icelandic reinforced confined concrete columns is according to the rules given in the European standards for design of concrete structures and earthquake resistance.

Structural Analysis of Aluminium Transmission Pylon. Author: Hannibal Þ. Ólafsson.
The main purpose of this study is to analyze a new type of pylon in terms of structural issues having aluminium as material ofthe structure. Linear and non-linear analyses are performed on the pylon. Aluminium alloys are studied to decide on type of alloys to be used.

Concrete walls founded on earthquake areas. Author: Helgi S. Ólafsson.
The main object of this project is to show how different foundations change the behavior of walls during seismic activity.The analysis of this behavior requires models that take into account not onlythe structure, but also the bedrock, soil bed and the dynamic interaction forces existing between them.  Link to thesis. 

Near-fault ground-motion and structural design issues. Author: Sigurður U. Sigurðsson.
An introduction to inelastic behaviour of elastic-perfectly-plastic (EPP) SDOF systems is presented using models relating structural behaviour factor and displacement ductility. Other types of inelastic hysteretic behaviour are compared with EPP system performance. Link to thesis.

The attempt in this thesis is to accumulate the main affects that concerns ventilated thin air gaps in roofs in Iceland and explain them with drawings, pictures and calculations.


Pushover analysis of an existing reinforced concrete structure. Author: Jón Ö. Bjarnason.
The main purpose of this study is to analyze the seismic response of a reinforced concrete structure which suffered damage in the South Iceland earthquakes in June 2000. Two different methods are used to analyse the structure.
