Nonlinear seismic response of 3D canyon in deep soft soils

Yantu gongcheng xuebao, 2017
A model is proposed for nonlinear seismic response of 3D canyon in deep soft soils. In the model, the viscous-elastic boundary and the equivalent node force input method are combined for wave motion input, and the equivalent linear method is introduced ...

Seismic behavior of pile group in soil slope

, 2021
Seismic behavior of pile group in slope is interested for many years by researchers .Inthis research Shaking table tests were conducted by means of a rigid-box with 1.8m in length,0.8 in width and 1.2 in height in order to investigate the effects of the location of pile group insand slope on its seismic behavior .A cap supported by a pile group was set

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Investigation of ground motion vertical and horizontal component effects on the IDA curves for the regular and irregular steel moment frames [PDF]

Journal of Structural and Construction Engineering, 2019
The effect of seismic vertical components on the seismic behavior of structural systems can be considerable. The vertical component of ground motion records can cause the brittle collapse of columns resulting in global collapse of structures. This effect

Assessment of Seismic Behavior of an RC Precast Building [PDF]

, 2020
Past earthquakes brought attention to the poor performance of precast reinforced concrete structures. One of the problems observed in those structures is related to the beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is an important aspect that should be ...

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Analytical Pushover Curves for X-Concentric Braced Steel Frames

Buildings, 2022
In this work, analytical pushover curves for concentric braced steel frames with active tension diagonal bracings (X-CBF) are proposed. A pushover “spindle”, characterized by two trilinear analytical capacity curves defined for an X-CBF system subjected ...
