Part 1 Stability of the structure: structure and stability - stability and structural form, instability and appraisal, stability and deficiency, instability and deficiency, overview of domestic construction before and after World War I, low-rise forms of non-traditional construction, industrialized and system-built forms of construction, general defects in non-traditional construction; distortion and criteria - categorization of building damage, monitoring crack symptoms, measurement tools, types of movement, criteria for the measurement of distortion, verticality and twist; the influence of structural form on failure symptoms - loading and stability, acquired deflections in structures, location of stresses, connections between structures, movement and structural form, movement and deformation, restraint and connectivity, openings and stress concentration, exposure and stress location; instability - the role of external forces - wind loading, snow loading, seismic shock, vibration, mining activity, accidental impact damage, explosions; instability - structural form and deficiency - inadequate loadbearing capacity, inadequate restraining of elements, lateral and longitudinal instability, instability of untied elements, interaction and instability, cracking and structural movement, overloading of the structure; instability of the structure - the role of substructure - foundation failure, soil overload, load transference failure, wholesale ground movement, differential ground movement, clay soils, the role of trees in foundation failure; instability in the fabric - permeable and impermeable envelopes; instability in materials - material-induced instability, deterioration of materials, chloride attack, sulphate attack, environmental pollution, aggregate problems, frost attack, carbonation, corrosion, metals generally; dimensional instability - moisture movement - dimensional instability of materials, moisture-related movements, the role of climate, symptoms generally, irreversible movement defects, irreversible expansion and shrinkage, conflicts of expansion and contraction, reversible movement defects, constructional detailing; dimensional instability - thermal movement, temperature-related movements, symptoms generally, rigidity and flexibility, mitigating factors, constructional detailing. Part 2 Hygrothermal deficiency: penetration of the envelope by solids - wind and air tightness. Part contents.
