Seismic performance of 1/4-scale RC frames subjected to axial and cyclic reversed lateral loads
Masanobu Sakashita,Susumu Kono,Fumio Watanabe,Hakim Bechtoula 한국계산역학회 2005 Computers and Concrete, An International Journal Vol.2 No.2
This paper summarizes an experimental study on the seismic behavior of lower stories of a mid-rise reinforced concrete frame building. Two reinforced concrete frames with two stories and one span were tested and each frame represents lower two stories of an 11-story RC frame building. Both frames were designed in accordance with Japanese design guidelines and were identical except in the variation of axial force. The tests demonstrated that the overall load-displacement relations of the two frames were nearly the same and the first-story column shear was closely related to the column axial load. The columns and beams elongated during both of the tests, with the second-floor beam elongation exceeding 1.5% of the beam clear span length. The frame with higher axial loads developed more cracks that the frame under moderate axial load.
A scheme on multi-tier heterogeneous networks for citywide damage monitoring in an earthquake
Fujiwara, Takahiro,Watanabe, Takashi,Shinozuka, Masanobu Techno-Press 2013 Smart Structures and Systems, An International Jou Vol.11 No.5
Quick, accurate damage monitoring is strongly required for damage assessment in the aftermath of a large natural disaster. Wireless sensor networks are promising technologies to acquire damage information in a citywide area. The wireless sensor networks, however, would be faced with difficulty to collect data in real-time and to expand the scalability of the networks. This paper discusses a scheme of network architecture to cove a whole city in multi-tier heterogeneous networks, which consist of wireless sensor networks, access networks and a backbone network. We first review previous studies for citywide damage monitoring, and then discuss the feature of multi-tier heterogeneous networks to cover a citywide area.
