Chile’s reinforced concrete (RC) design is based on ACI 318-08, where high-strength reinforcement not allowed in seismic force-resistant members. In 2019, new requirements adopted by 318 permitted the incorporation of walls. This study compared performance two Chilean 20-story residential buildings soft soil, one designed with traditional Grade 60 and other 80 reinforcement. The was assessed te...

Göçme öncesi sismik performans seviyesinde, kesmeye maruz betonarme kolonların yatay yük ve eksenel taşıma kapasitelerindeki azalmayı bu davranışların tüm yapıya etkilerini modellemeye tahmin etmeye ihtiyaç vardır. Kesme dayanımı ile deformasyon kapasite davranışlarının incelenmesi için farklı beton basınç dayanımı, seviyesi spiral donatı oranlarında dairesel kolon modelleri tasarlanmıştır. Tas...

This article represents the second report by an ASCE Task Committee "Infrastructure Impacts of Landscape-driven Weather Change" under the ASCE Watershed Management Technical Committee and the ASCE Hydroclimate Technical Committee. Herein, the 'infrastructure impacts" are referred to as infrastructure-sensitive changes in weather and climate patterns (extremes and non-extremes) that are modulate...

The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio State Department of Natural Resources (ODNR) issued new regulations in 1981 requiring that design flood for class I dams be considered equal to the Probable Maximum Flood (PMF). Flood routing studies performed...

Shallow Soil Mixing (SSM) is a sister technology to Deep Soil Mixing (DSM) developed to more economically improve soils within ten meters of the surface. SSM was recently utilized to provide a foundation for large effluent storage tanks as well as to contain foundation soils in the event of liquefaction from an earthquake. Two large storage tanks were required to be built in a pulp mill. The on...

This paper introduces a new approach for the seismic performance evaluation of planar RC walls. Compared to existing assessment guidelines, such as those in ASCE/SEI 41-17, where limits are described by plastic rotation or lateral drift, proposed method uses local (strain) quantities, obtained from computational models. The analyses rely on user-friendly implementation nonlinear truss model str...

The goal of this research was to investigate the potential of newly synthesized gold complex trichloro(2,4,6-trimethylpyridine)Au(III) as an anticancer agent. The gold(III) complex was synthesized and grafted on nanoporous silica, MCM-41, to produce AuCl(3)@PF-MCM- 41 (AuCl(3) grafted on pyridine-functionalized MCM-41). The toxicity of trichloro(2,4,6- trimethylpyridine)Au(III) and AuCl(3)@PF-M...

Channel estimation problem is one of key technical issues in time-variant multiple-input multiple-output (MIMO) communication systems. To estimate the MIMO channel, least mean square (LMS) algorithm was applied to adaptive channel estimation (ACE). Since the MIMO channel is often described by sparse channel model, such sparsity could be exploited and then estimation performance could be improve...

Sparse channel estimation problem is one of challenge technical issues in stable broadband wireless communications. Based on square error criterion (SEC), adaptive sparse channel estimation (ASCE) methods, e.g., zero-attracting least mean square error (ZA-LMS) algorithm and reweighted ZA-LMS (RZA-LMS) algorithm, have been proposed to mitigate noise interferences as well as to exploit the inhere...
