“…Since the development of the proposed gusset moment connection was originally inspired by the ongoing study of the steel plate shear wall system by the authors, the mesh refinement study and material properties are based on information in reference [5]. Plasticity with multi-linear kinematic hardening material model was used to better capture the Bauchinger effect.…”

-Steel moment frames are widely used in buildings subjected to lateral loads such as wind and earthquakes. This paper summarizes development of a new economical steel moment connection for use in highly seismic areas. The highly ductile new connection is primarily utilizing ductility of the gusset plate to provide necessary rotational capacity while the entire beam and column being connected remain essentially elastic. Due to the desirable performance of the connection and the flat geometry of the gusset plate, the proposed connection is well-suited to be used in steel and composite special ductile moment frames, special steel shear walls and dual systems of moment frames plus special concentrically braced frames, all currently used in seismic lateral force resistance in buildings. The proposed new moment connection can also be used in resisting gravity loads and lateral forces due to wind. In the proposed gusset plate moment connection, the beam is cut short to leave a distance from the column face where yielding and plastic hinge formation are expected to occur primarily due to in-plane yielding of the gusset plate. The gusset plate can either be directly welded to the column or bolted to the column using an end plate. With careful proportioning and proper detailing, the beam is expected to remain essentially elastic during the cyclic loading and no, or minimum continuity plates will be required for the column panel zone. Extensive nonlinear finite element analyses have been conducted. The results indicated that the connection will be very ductile and performs in a very desirable manner when the moment capacity of the gusset plate divided by the moment capacity of the beam ratio is less than 1.0, the thickness of the gusset plate is equal or greater than 1.25 times the beam web thickness and the free gusset plate length is equal to 4 to 6 times the gusset plate thickness. Based on the observation from the studies summarized herein, the use of "Upset bolts" is recommended for the bolted version, where tension bolts connect the gusset plate to the column.

“…Three cases represent the new HPSPSW system, where the thicknesses of the steel shear walls and side stiffeners were varied. They were designed based on the dimensions of Park SC4T specimen (Park et al, 2007). The other model was modified from the original test Specimen SC4T to the boundary condition of the current study that represents a current steel plate shear wall system, where the steel plate is welded to the columns and the beam-to-column connections are traditional field-welded connections.…”

Abstract:To date, the design of unstiffened steel shear walls has three issues that make them expensive to employ: 1) large columns resulting from the shear wall applying lateral loads to the columns; 2) expensive field-welded moment connections; 3) buckling of the steel plate under service earthquakes and winds. A new, innovative system, called the high-performance steel shear wall system, is developed and proposed by the authors to solve these problems. In this system: 1) the steel plate shear wall is not connected to the columns, therefore, the columns do not experience large lateral forces; 2) the beam-to-column connections consist of an innovative and cost-effective connection developed by the authors, referred to as a gusset plate moment connection; 3) the thickness of the plate is independent of the column size, enabling the use of thicker plates to prevent buckling of the steel plate under service loads.Keywords: steel shear wall; structural engineering; earthquake engineering; design of steel structures; seismic design; moment connections; gusset plate; performance-based design; design for wind; tall buildings; welds; bolts; steel construction; retrofit of buildings; modular construction.Reference to this paper should be made as follows: Qian, X. and Astaneh-Asl, A.

As a detailing solution which would reduce the discontinuity Park et al [27] proposed enhanced detail as given in Fig. 8a, while Choi and Park [15] proposed dislocation of the fish plate welded connection towards beam mid-span in order to prevent early fracture due to stress concentration at the joints as shown in Fig.…”

Subject reviewApplication of vertical stabilisation systems composed of frames with infilled panel has been increasingly adopted in nowadays buildings, primarily due to high resistance as well as their favourable behaviour when exposed to significant seismic activity. This paper has covered systems consisting of composite panels placed within the steel or composite member frames. These systems are listed in leading world norms, but the given guidelines are, due to insufficient research, very scarce and leave the designer with a number of opened questions. Aside these guidelines, this paper provides their additional clarification, and indicates the field's current state of the art which would be used to set the course of further research. Keywords: composite plate shear walls; seismic activity; shear wall; vertical stabilisationStanje područja ponašanja i proračuna sustava vertikalne stabilizacije koji koriste spregnuti ispun Pregledni članak Primjena sustava vertikalne stabilizacije sastavljenih od okvira s umetnutim ispunom sve više nalazi mjesta u današnjim građevinama, prvenstveno iz razloga velike otpornosti kao i dobrog ponašanja uslijed značajnijih potresnih djelovanja. U radu su obrađeni sustavi sa spregnutim ispunom, te okvirom izvedenim od čeličnih ili spregnutih elemenata. Takvi su sustavi navedeni u normama, ali su dane smjernice, iz razloga nedostatne istraženosti, vrlo šture i ostavljaju mnogo otvorenih pitanja. Rad uz smjernice iz vodećih svjetskih normi navodi pojašnjenja istih, te dodatno ukazuje na sadašnje stanje područja na temelju čega je moguće iščitati smjernice za buduća istraživanja.Ključne riječi: posmične stijene; seizmičko djelovanje; spregnuti ispun od čelika i betona; vertikalna stabilizacija
