List of tallest buildings in Christchurch Road and bridge damage occurred and hampered rescue efforts. Damage occurred to many older buildings, particularly those with unreinforced masonry and those built before stringent earthquakes codes were introduced.

What types of products does Simpson Strong-Tie produce? Barclay Simpson, founder of the company, made his first connecter — a joist hanger — in Today, Simpson Strong-Tie Earthquake safety thousands of structural connectors, including joist hangers, hurricane ties, straps and holdowns.

In addition to structural connectors, the company offers fasteners, anchor systems, shearwalls, multistory tiedown systems, and fastening tools. These products help improve the strength and safety of homes and buildings. What is a connector? Structural connectors are Earthquake safety out of steel, and are engineered to connect and strengthen the frame of a home.

Reinforcing the frame of a home with structural connectors helps the home resist damage caused by earthquakes, high winds and hurricanes. Framing materials secured with connectors are much stronger than if secured only with nails called toe-nailing.

Resetting Your Valve

Connectors come in all shapes and sizes, and have a variety of names, such as joist hangers, holdowns and hurricane ties. Homeowners don't typically see connectors in their homes because they are covered up behind the walls.

What is a fastener? Fasteners typically refer to nails, screws, bolts or anchors. Fasteners are used with connectors to attach framing materials together, such as wood, masonry and concrete.

What is a shearwall? Shearwalls are reinforced walls within a home that have been engineered to help resist the shear racking forces that are caused by high winds or lateral forces that are caused by earthquakes.

Shearwalls are typically constructed by attaching wood sheathing and holdown connectors to a section of the wood framing along a wall. What is a continuous load path and why is it important for a home?

A continuous load path is a method of construction that uses a system of wood, metal connectors, fasteners like nails and screws and shearwalls to connect the structural frame of the house together. It ties the house together from the roof to the foundation. A continuous load path is important because it helps redistribute outside pressures or forces caused by earthquakes and high winds, transferring these external forces from the frame to the foundation, which is securely anchored into the ground.

A home with a continuous load path is much better equipped to withstand the strong forces caused by high winds, tornadoes, hurricanes and earthquakes. When framing a house, why is it better to use connectors than the historic practice of toe-nailing?

Framing materials held together with structural connectors can withstand much stronger forces than if held together with nails. Connectors have what is called a higher load capacity than nails see example below.

Earthquake safety

In a high wind storm, for example, nails are much more likely to pull apart or pop out than a metal connector. A connection made with a metal connector can be pulled apart, but it takes much greater force to separate it than a simple toe-nailed connection.

A home built with connectors is better able to resist forces from high winds and earthquakes.


Are structural connectors and a continuous load path necessary if you don't live in an area prone to high winds or earthquakes? The National Oceanic and Atmospheric Association, which tracks weather events, reports that all 48 continental U.

And while hurricanes typically affect coastal regions, all states are subject to high wind storms. Making sure your home is built with connectors and a continuous load path can help protect your home and your family when an unexpected weather event happens.An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic monstermanfilm.comuakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities.

Earthquake Retrofitting and Seismic Upgrades Many of our customers tell us they do not know what questions they should be asking. While the basics of earthquake retrofitting are simple, the retrofitting process can be complex.

An Excess Flow Valve, or EFV, is a safety device installed on natural gas distribution pipelines to automatically close and restrict the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter.

Earthquake Safety Tips How to stay safe when these natural disasters strike Earthquakes are a common occurrence, rumbling below Earth's surface thousands of times every day. 2 Earthquake Safety Checklist Have on Hand for Any Emergency – Ideas for Home, Workplace, and Car Because you don’t know where you will be when an earthquake .

The Northridge valve is a simple patented design with only one moving internal part. A stainless steel ball rests on a pedestal inside the valve when it is in the ON position allowing gas to flow.

During a seismic disturbance of approximately or greater on the Richter scale, the stainless steel ball falls from the pedestal and plugs the outlet passage stopping the flow of gas.
