Experimental study on the influence of slab’s reinforcement on seismic bearing capacity of beam’s cross-section in cast-in-situ frame structure Jinshi Guo1, a Xinying Xie1,b 1Jilin architectural and civil engineering institute,Changchun,China aguojinshi_2006@163.com,b83518448@qq.com Keywords: Floor slab reinforcement;rigidity of orthogonal beam;strong column and weak beam;the effective flange width Abstract.
“strong beam and weak column”is the main failure states of reinforced concrete frame structure in the earthquake.This paper is the experimental study of the influence on the virtual cross-section bearing capacity on extremity of frame beam in reinforced concrete,which is affected by some element,such as slab reinforcement,the rigidity of orthogonal beam and so on.Exploring the mechanism of slab and frame work together to determine the width of effective flange,which provides references for structural design and engineering application.
to collapse while the beam and slab work together without any damag after investigation.The failure of cast-in-situ in concrete frame structure in this earthquake performs”strong beam and weak column”,and these are designed according to the standard of”strong column and weak beam”,also formed column hinge joint.The main reason is that the increase influence of cast-in-situ slab flexural capacity of the beam section is not considered.In order to increase the difficulty of implementation,the code for seismic design of buildings did not make specific provisions for how to consider the effect of the reinforcement of the frame beam slab actual bearing capacity of normal section.This paper is the experimental study of the influence on the virtual cross-section bearing capacity on extremity of frame beam in steel reinforced concrete,depends on slab reinforcement and the rigidity of orthogonal beam.Exploring the floor in mechanism of frame work,which provides reference for structure design and engineering

Wireless sensor network was established based on ZigBee technology, then planar landslide information acquisition transmission system was developed, and immediately applied in engineering fields.
(2) Conditions in the landslide monitoring site are complex and changeable, monitoring points may need to be added, removed, or mobilized at any time for engineering requirements, the characteristics of wireless sensor network, especially flexible network mode of the system is cater to the needs of the consumers

The Elastic-Plasticity Analysis on Cross-Section Short-Limb Shear Wall Qiang Zhang1, a, Cheng-cheng Tao1, Chen-bing Wei1, Jian Zhuang1, Pei Tan1, You-hai Liang2 1College of Civil Engineering, Shanghai Normal University, Shanghai 201418, China 2College of Science, China Agricultural University, Beijing 100083, China a zhq@shnu.edu.cn Keywords: Cross-Section Short-Limb Shear Wall; Elastic-Plasticity Analysis; Load Capacity, Deformation Capacity; Concrete Strength Grade; Limb-Length Ratio Abstract.
The analysis results show that when concrete strength grade is C30, shear wall of this shape can be made with better performances in load capacity and deformation capacity, and when limb-length ratio is 0.6, the ductility and the ability of the energy dissipation of shear wall is not good, which provides a significant basis for practical engineering section design.
Introduction Short-limb shear wall structure [1] is a new lateral-force-resistance system which is come up with by the engineering structure designers of our country.
