Sentence examples for under the design level from inspiring English sources

This configuration was quite flexible and suffered large deformations under the design level earthquake.

It was stipulated that the prestress force in the walls should provide sufficient moment capacity to limit the wall drift ratio to 2% under the design level earthquake.

For example in a building structure, due to the limited deformation capacity of non-structural elements and to control damage at life safety design level, the inter-story drift under the design level earthquake should not exceed 2% (IBC 2006; Priestley 2002).

Focusing on a six-story demonstration CBF which has representative geometries, the SMABs were designed to enable the demonstration CBF to achieve similar maximum transient inter-story drift responses to the same CBF consisting of the BRBs under the design-level earthquake excitations.

This paper presents a numerical study on collapse analysis of existing high-rise SMRFs under long period ground motions over the design levels.

Recently, a design modification has been proposed for eccentric, torsionally stiff, braced steel buildings, designed according to the current Eurocodes 3 and 8, that improves noticeably their inelastic response under the action of design level earthquakes.

Consequently, traditional friction dampers may function well under earthquakes with the intended design level, but may not be functional for earthquakes with lower intensities.

Ring spring contribution of 40% improved the self-centering properties, resulting in residual drifts less than 0.1% under design level shaking.

Many researchers have shown that SCBFs designed by conventional elastic design method suffered severe damage or even collapse under design level ground motion (MacRae et al. 2004; Broderick et al. 2008; Richards 2009; Roeder et al. 2011).

This paper aims at determining the optimal number of new facilities besides specifying both the optimal location and design level of them under the budget constraint in a competitive environment by a novel hybrid continuous and discrete firefly algorithm.

The performances of the building under multiple earthquake design levels are finally verified through non-linear time-history analyses whose results confirm the effectiveness of the proposed approach.
