WEEK 7: DEATALING STRATEGIES Define arches: curved structure for spanning and opening to support vertical loads through axial compression.
(Ching, 2008) Define dome: spherical surface with a circular plan, stacked blocks, continuous rigid structure. Difference: circumferential forces; compressive at the crown and tensile near the bottom. Define shells: thin, curved plate. Transmits applied forces by membrane structures. Little bending resistance. MOISTURE AND THERMAL PROTECTION
1. Flashing: continuous sheet metal used to prevent passage of water into structure from angle of joint.
2. Parapet
3. Fascia: metal covering to conceal guttering. VENTILATION ISSUES: - Incorrect insulation type and installation - Environmental quality – pollutants managed, distributed and removed - Long-‐term issues – sick building syndrome
