“…The specimen outlines and reinforcement details are presented in Todut et al [27,28]. The strengthened elements were renamed using a specific notation: the suffix T/R refers to elements initially tested prior to failure, thereafter retrofitted and retested; R/T for elements retrofitted initially on undamaged elements and tested; and the reference elements tested initially have the suffix (T).…”

“…M30 indicates that the bolt has a diameter of 30 mm. Bolts made of low-carbon alloy steel or medium-carbon steel and subjected to heat treatment (quenching and tempering) are known as highstrength bolts, and the remaining are collectively referred to as ordinary bolts (Todut, Dan, and Stoian 2014). Figure 24 shows a reinforcement drawing of the test piece.…”

Joints lead to the uneven distribution of structural rigidity of a precast prestressed utility tunnel (PPUT) and changes in internal forces and deformation. From research perspective, bending stiffness is important as an important indicator to evaluate the performance of PPUT joints and an important factor to evaluate the overall mechanical properties of PPUT structures. After considering the actual structural form of a transverse joint section and the characteristics of force deformation, a mechanical model that can characterize the joint section from force to failure and the corresponding analytical expressions were established using the internal force balance and deformation coordination conditions. A sensitivity analysis of the factors affecting the bending stiffness of joints was carried out using numerical simulation methods. The theoretical calculation results were compared with the numerical simulation results. Finally, according to the obtained trend of bending stiffness change, a two-stage bending stiffness method is proposed for the transverse joints of PPUT. The results of the study provide a reference for the design and theoretical analysis of PPUT.

“…The deformation capacity of precast walls was inferior to cast-in-situ walls, but both ultimate displacement drifts exceeded 1/100. Ductility evaluation remains conventional because of the difficulty in a well-defined yield point [13,17]. Park [18], Priestley [19], and Salonikios et al [20] have devoted research to the yield displacement.…”

An innovative joint connecting beam for precast concrete shear wall structuresThe precast shear wall structure has outstanding features for green buildings due to its construction convenience, safety, high quality and low pollution. In general, precast concrete shear walls are connected by multiple joints. The joint between precast walls has very strong influence on the whole structure, which calls for more detailed investigation. A new kind of connection -the joint connecting beam -was developed to connect the vertical reinforcement in precast concrete shear wall structures. This innovative connecting method has the advantages of convenient operation and saving steel. To evaluate the performance and for better application of the joint connecting beam, an experiment on seven full-scale specimens was conducted under cyclic loading, including two cast-in-situ walls and five precast walls with varying reinforcement and sectional heights of the joint connecting beam. A comparison was performed between cast-in-situ walls and precast walls with joint connecting beam, focusing on failure mode, hysteretic curve, skeleton curve, bearing capacity, ductility and energy-dissipating capacity. The results show that the joint connecting beam can effectively transfer the load of precast walls, especially for squat precast walls. Moreover, finite element models were developed to simulate the performance of the specimens. The simulation results agree well with experimental results.
