Design of Tied‐Back Walls for Seismic Loading

Journal of Geotechnical Engineering, 1992
A finite element model is used to evaluate seismic behavior of static and seismic tiedback retaining wall designs. Two static designs are tested. The first design assumes active earth pressure resulting in a single‐anchor design. The second static design uses a rectangular apparent‐pressure diagram, resulting in a two‐anchor wall. These two designs are

ANALYSIS AND DESIGN OF STAIRCASES AGAINST SEISMIC LOADINGS

Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2014
In this work all types of staircases are studied with respect to: First, earthquake design requirements and second, their complex interactions with the multistory space frame in which they belong. In the first case the essential influence of the vertical component of the earthquake’s acceleration on the structure’s performance is examined.

A method of bridgework design for seismic loads

Mechanics of Solids, 2015
Analyzing the action of seismic loads on bridgework is a very topical problem of structure dynamics. These studies combine two independently developing areas of research which include the design of transport structures only for seismic loads [1–14] and the design of structures for the action of inertial moving load [15–28].

Determination of the level of seismic danger and design seismic loads for large hydrotechnical structures

Power Technology and Engineering, 2006
A local network of sensitive high-accuracy seismological stations has to be created for seismological observations near a hydrotechnical structure and on the banks of the storage reservoir. The layout of the network is chosen with allowance for the configuration of the reservoir and for the location of the seismogenerating zone relative to the ...

Analysis and Design of EPS-Geofoam Embankments for Seismic Loading

Geotechnical Engineering for Transportation Projects, 2004
The use of block-molded expanded polystyrene (EPS-block) geofoam as a lightweight-fill material for highway embankments is a relatively mature geotechnology with more than 30 years history of successful application worldwide. Basic analysis and design procedures are now well established and documented, and current research and development efforts are ...

OPTIMUM DESIGN OF SPACE FRAMES UNDER SEISMIC LOADING

International Journal of Structural Stability and Dynamics, 2001
The objective of this paper is to perform structural optimization under seismic loading. Combinatorial optimization methods and in particular algorithms based on Evolution Strategies are implemented for the solution of large-scale structural optimization problems under seismic loading.

METHODS FOR COMBINING LOADS IN THE DESIGN OF THE SEISMIC STABILITY STRUCTURES

STRUCTURAL MECHANICS AND ANALYSIS OF CONSTRUCTIONS, 2022
The ways of combining loads in evaluating strains and other indicators of the structure operation are considered. The main attention is paid to two methods: constructing the distribution density function of the analyzed factor caused by the simultaneous action of loads and the analysis of equiprobable pairs of the considered loads.

A Design of anchors in masonry under seismic loads

2020
Fastenings to set up technical equipment, façade, and secondary structural components, are widely used in building construction. Their static design, which depends on the type of support systems and anchors, is clearly defined in standard codes. However, a lack of standard design rules under seismic loadings in masonry support is noticed.

Design of Anchor Reinforcement for Seismic Shear Loads

ACI Structural Journal, 2013
Existing design codes recommend hairpins and surface reinforcement consisting of hooked bars encasing an edge reinforcement to improve the behavior of anchor connections in shear. Concrete breakout is assumed to occur before anchor reinforcement takes effect in the current design methods.

Assessing tsunami vulnerability of structures designed for seismic loading

International Journal of Disaster Risk Reduction, 2014
Wave movement with large velocity triggered by strong earthquake occurring at the sea bed is generally the primary cause of the tsunami. Occurrence of tsunami (like the one during the Sumatra earthquake in 2004 or the one during the Tohoku earthquake in Japan in 2011) causes devastating damages to the coastal structures and tremendous casualties ...
