Indoor Air Quality Impacts Into Life Cycle Assessments Of Buildings And Building, Afrim Syla

UBT International Conference

Human exposure to indoor pollutant concentrations is receiving in-creasing interest in Life Cycle Assessment (LCA). Products used during con-struction and operation of a building can contribute to Indoor Air Quality (IAQ) problems that affect occupants’ well-being. However, IAQ is conventionally not addressed in the life cycle assessments (LCAs) of buildings and building re-lated products even though IAQ leads to one of the areas of protection under LCA - human health impacts. In this study, we proposed an overall framework for integrating IAQ into LCA using the standard steps of LCA. The framework focused on IAQ and LCA modeling from two …

Dynamics Of Simply Supported Beam Members Subject To Vertical Seismic Acceleratio, Francesco Foti, Luca Capacci, Bruno Dal Lago

UBT International Conference

Despite in most cases vertical seismic acceleration is disregarded in practical structural design, mainly due to the uncritical actions of the pertinent load combination, current standards prescribe the structural check of long-span and pre-stressed beam members subjected to vertical acceleration when they are located in high seismic hazard areas. Current design approaches focus on either finite element calculation, which does not provide a logical guidance to the designer for the problem, or, alternatively, on simplified calculations typically assuming lumped masses concentrated at midspan of the horizontal member. The latter approach does provide only an indicative solution affected by arbitrary modelling …
