Continuous girder bridges have been extensively constructed in China over the past 30 years, and these tend to experience severe damage under ground motions with velocity pulses. In current research, an innovative linear friction damper (LFD) is proposed mitigate seismic damages of continuous subjected near-fault motions. The OpenSees platform adopted establish numerical model a bridge region. ...

labeling, but has found none that would achieve the objective of this ban, consistent with the public health and safety. (2) The Commission believes that any adverse effects of the ban should be minimal and would be expected to be confined to some shift in distribution patterns to accommodate professional users, including methods of distinguishing between professional users and consumers. (3) T...

The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...

Lead rubber isolation bearings are well-recognized as a common and effective means to mitigate the seismic responses of bridges. However, used in offshore bridges extremely vulnerable action alternation aging seawater erosion caused by weather conditions, wind, waves, other factors. Meanwhile, deterioration law application lead subject effect cycles not clear. Thus, testing on both (LRB) materi...

In this proposal the mechanical properties of natural and synthetic rubbers are studied under different temperatures both real ageing heat treatment conditions. For purpose, tire rubber bearing pad considered as they most governed in respectively. The experimental results confirm that impact temperature is higher on than because ambient aggravate thermal motion changes molecular arrangement oth...

The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented. An example calculation of rolling resistance for a polyurethane tire is giv...
