Water Damage By the Numbers

Home Water Damage.When you consider the statistics,it becomes clear just how common and devastating a problem water damage can be.According to industry estimates,14,000 people in the US experience a water damage emergency at home or work each day,and 98% of basements in the US will suffer from some type of water damage during their lifetime.Uncertainty analysis for the net-section-collapse failure In this paper (part I),a generalized NSC method is presented to predict the maximum moment of a circumferentially cracked pipe with a variable-depth internal surface crack subject to combined Strain-Based Failure Assessment Based on a Reference One of the effective methods for improving the accuracy of strain-based ECA is the reference strain method.However,only a limited number of studies have applied this method to welded pipelines.Therefore,a numerical analysis based on strain-based ECA was performed for girth-welded joints with a circumferentially oriented internal surface crack.
