  abstract  = {This paper presents the development of an assessment scheme for a visual qualitative evaluation of nailed connections in existing structures, such as board trusses. In terms of further use and preservation, a quick visual inspection will help to evaluate the quality of a structure regarding its load-bearing capacity and deformation behaviour. Tests of old and new nailed joints in combination with a rating scheme point out the correlation between the load-bearing capacity and condition of a joint. Old joints of comparatively good condition tend to exhibit better results than those of poor condition. Moreover, aged joints are generally more load-bearing than newly assembled ones.},

  abstract  = {This paper presents initial findings from the empirical analysis of community based social enterprise (SE) and non-profit organisation (NPO) ecosystems in Johannesburg. SEs and NPOs are widely recognised as contributors to the resilience of marginalised urban communities. However, the connection between these organisations , urban governance, and community resilience has not yet been sufficiently understood , particularly in African urban contexts. The 'Resilient Urban Communities' project focuses on Johannesburg as a case study to shed light on this under-researched topic. The key to exploring it is understanding SEs and NPOs as providers of public services, job creators, and promoters of good governance, all of which contribute to community resilience. Using this premise as a starting point, this paper investigates ecosystem conditions with a particular focus on state-civil society partnerships. Empirical data was generated through semi-struc-tured interviews and analysed with a grounded theory approach. Preliminary results of this ongoing research reveal that urban geography is a relevant ecosystem factor for SEs and NPOs from marginalised communities. We also suggest that co-production could be an opportunity for growth within the investigated state-civil society partnership.},

  title     = {TESTING OF CONNECTIONS TAKEN FROM OLD NAILED ROOF TRUSSES},

  pages     = {8},
  abstract  = {Experimental testing of nailed connections taken from old roof trusses is presented in this paper. To enable the further use and preservation of nailed roof trusses, it is important to understand how the nail corrosion and aging processes of steel and wood affect the load-bearing capacity and deformation behaviour of such structures. The hypothesis was investigated whether corroded nails allow an increase in load-bearing capacity. Several old and new joints were tested in a first test series, and the results were very promising regarding the initial assumption. However, more tests must be carried out to verify the results.},
