Research Abstract

In order to provide high performance building envelopes as a counter measure against the climate change issues, a durability assessment of composite steel walls are the one of the important engineering challenges to be solved in ner future, It should be required a jointed technology of numerical simulation procedures for the long term hygrothermal performances on building envelopes with metallic elements and corrosion performance predictions on them.
In this investigation, we have developed a numerical procedure to predict both hygrothermal and corrosion performances for multi-dimensional composite building envelopes with metallic elements. Multi dimensional heat, air and moisture transfer has been formulated by the boundary element techniques. Numerical evaluation procedures were proposed for boundary integrals and domain integrals with both numerical efficiency and accuracy. A simple and robust procedure to describe boundaries and interfaces for arbitrarily connected heterogeneous bod … More ies has been described which can reduce computational resources for pivoting coefficients for solving the system of equations. Couples of simple thermal problems have been analysed as numerical demonstrations.
In the sixth chapter, in situ monitored experimental data on the real scaled exterior insulation wall with vented cavity has been analysed in order to demonstrate usefulness and applicability of the proposed method for hygrothermal and corrosion performances. The monitored wall with vented cavity devised aluminum exterior cladding supported by SUS pillars. The differences on thermal performances and moisture and corrosion performances as well, have been evaluated. The merging these monitored data can create important opportunity to compare and validate the whole numerical procedure. Besides it also provide opportunity for experimental evaluations on following aspects : (1) Hygrothermal performances of a vented cavity wall, (2) the air flow and dehumidification characteristics of the cavity, and (3) improving thermal and economical performance of pillars fabricated by stainless-steel or aluminum which support the finish layer. In this paper, the experimental setup and the measurement plan are described and measured data on recent hygrothermal situations of wall systems are presented. Less
