1. A ground-borne noise prediction model for railway traffic in tunnels in bedrock
Sammanfattning : Human life has become more manageable by the expansion of railway lines. However, despite providing convenience, railways increase noise and vibration in residential areas. Vibrations and noise generated by railways may harm human health, cause cosmetic damage and have an adverse impact on the environment. LÄS MER
2. Computational Methods in Conceptual Structural Design
Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER
3. Vibrations from Railway Traffic : Computational Modeling and Analysis
Sammanfattning : The population is growing, and an increasing proportion of the population lives in urban areas. As a consequence, human exposure to noise and vibrations is increasing; two major sources being railway and road traffic. Larger and denser cities lead to a higher amount of traffic close to where people work and live. LÄS MER
4. Inventory of geomechanical phenomena related to train-induced vibrations from tunnels
Sammanfattning : Banverket is expecting that the number of railway tunnels in densely populated areas will increase over the next 20 years due to the lack of available space on the ground surface, but also since the railway is considered an environmentally friendly solution of transportation for the future. The need for good predictions of vibration and noise levels in dwellings along the planned tunnels is therefore evident. LÄS MER
5. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay
Sammanfattning : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. LÄS MER
