摘要：This paper studies the seismic performance of FRP-strengthened RC interior non-seismically detailed beam-wide columns and beam-wall joints after limited seismic *** eccentric and concentric beam-wide column joints and two beam-wall joints,initially damaged in a previous study,were repaired and tested under constant axial loads(0.1fc′Ag and 0.35fc′Ag) and lateral cyclic *** rapid repair technique developed,aimed to restore the original strength and to provide minimum drift *** repair schemes were characterized by the use of:(a) epoxy injections and polymer modified cementitious mortar to seal the cracks and replace spalled concrete;and(b) glass(GFRP) and carbon(CFRP) sheets to enhance the joint *** FRP sheets were effectively prevented against possible debonding through the use of fiber *** between responses of specimens before and after repair clearly indicated reasonable restoration in strength,drift capacity,stiffness and cumulative energy dissipation *** specimens failed with delamination of FRP sheets at beam-column joint *** rapid repair technique developed in this study is recommended for mass upgrading or repair of earthquake damaged beam-column joints.

摘要：Metal-based secondary building unit and the shape of organic ligands are the two crucial factors for determining the final topology of metal-organic materials.A careful choice of organic and inorganic structural building units occasionally produces unexpected structures,facilitating deeper fundamental understanding of coordination-driven self-assembly behind metal-organic ***,we have synthesized a triangular metal-organic polygon(MOT-1),assembled from bulky tetramethyl terephthalate and Zr-based secondary building ***,the Zr-based secondary building unit serves as an unusual ditopic Zr-connector,toform metal-organic polygon MOT-1,proven to be a good candidate for water adsorption with *** study highlights the interplay of the geometrically frustrated ligand and secondary building unit in controlling the connectivity of metal-organic *** a strategy can be further used to unveil a new class of metal-organic materials.

摘要：The use of commercial products such as a cup and liner for total hip arthroplasty for patients with severe bone defects has a high probability of *** these patients the cup alone cannot cover the bone defect,and thus,an additional augment or cage is *** this study,we designed three-dimensional(3D)printable bone augments as an alternative to surgeries using reinforcement ***-five sharp-edged bone augments of various sizes were 3D printed.A biporous structure was designed to reduce the weight of the augment and to facilitate bone *** types of frames were used to prevent damage to the augment’s porous structure and maintain its stability during ***,two types of holes were provided for easy augment fixation at various *** tests were performed on a combination of worst-case sizes derived using finite element *** test results confirmed the structural stability of the specimens at a load of 5340 *** the porosity of the specimens was measured to be 63.70%,it cannot be said that the porous nature was uniformly distributed because porosity tests were performed locally and *** summary,3D-printable biporous bone augments capable of bonding from various angles and bidirectionally through angulation and bottom-plane screw holes are *** mechanical results with bone augments indicate good structural safety in ***,further research is necessary to study the clinical applications of the proposed bone augment.
