The bolted connections with slotted-in steel plates are basic beam-to-column connections of modern post-and-beam timber building structures. However, due to significantly pinched rotational behaviors, the moment resistance of such connections are usually ignored in design. In this study, the connection-level moment resistance is enabled for modern...

Currently, there is no “timber moment frame structural system,” as the basic glulam beam‐to‐column connections (usually represented by the bolted connections with slotted‐in steel plates) offer limited rotational stiffness such that they are usually treated as pin connections. This paper proposes an innovative type of moment‐resisting glulam beam‐t...

Dowel-type joints are commonly used as shear connections in many types of timber structures. The load-deformation hysteretic behavior of dowel-type joints usually dominates the structural seismic performance. In this paper, a novel phenomenological uniaxial hysteretic model for dowel-type timber joints is developed. It has the following features: (...

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation for a type of timber-steel hybrid structure that incorporates prefabricated light wood-frame shear walls into steel mom...

A slip-frictional damper connection with a lock-up system between walls and frames in hybrid steel frame and light wood shear wall systems is proposed to protect the main structural components from damage under earthquakes and expedite the post-earthquake recovery process. This paper presents quasi-static tests on six single-story-single-span plana...

This paper presents the calibration of performance objectives and the development of a performance-based design method for timber–steel hybrid structures that consist of a steel moment-resisting frame and prefabricated infill light frame wood shear walls. Interstory drift was adopted as the indicator of structural or nonstructural damage. One hundr...

With urban expansion, timber structures are no longer confined to low-rise buildings. The hybridization of timber with other construction materials is an effective way to obtain desirable structural performance while maintaining the many advantages of timber buildings. This paper is devoted to the development of a hybrid structural system which con...

Timber shear wall-steel frame hybrid structure has been proved to be an effective lateral load resisting system. However, timber shear walls will suffer from unrepairable damage under seismic loading. They should be demolished and rebuilt in this situation, which is costly and time consuming. In this study, supplemental slot-bolted dampers are intr...
