Firstly, the stress concentration factors at the joint intersection were measured.
This leads to investigation of the offset of joint intersection at the intersection and its relevant geometry and kinematics.
Block theory provides the removable joint pyramids from a given free surface regardless of the number of joints in any joint intersection.
For steel concrete PVC SHS joints with small φ ratio, the root of brace yielded first, while in the ultimate limit state, chord member around the joint intersection region were in the elastic phase.
For steel concrete PVC SHS joints with large φ ratio, chord member around the joint intersection region yielded first, while in the ultimate limit state, the root of brace were fundamentally in the elastic phase.
The database of thin shell finite element results generated was then used to develop parametric equations for predicting stress concentration factors at key locations around the joint intersection on the outer, as well as the inner, surfaces of the chord.
We develop here a rigorous joint intersection probability expression based on simple frequency probability considerations which predicts that the probability for x in the rock mass to fall in joint intersection Li,j,k is inversely proportional to the volume of the parallelepiped formed by joints i,j,k with mean spacing values xi, xj, xk P(x∈Li,j,k)="1/Vi,j,k∑l≠r≠s= 1m1/Vl,r,r.
Testing apparatus was designed to evaluate the waterproof capacity of the three types of segmental joints (i.e., longitudinal/circumferential joint and T-joint (intersection of longitudinal and circumferential joints)) in the Nanjing Weisan Rd.
Wheeler, a 22-year-old right-hander, was found Wednesday to have mild inflammation in his right acromioclavicular joint, the intersection of the shoulder blade and the collarbone, but no structural damage.
